No way No how any flash will give you +94hp (286 to 380) on a evoIX with the same fuel .
other tuner can do the same flash +/- for less , WAY less that $750
and there dyno chart only shows 45hp gain (and thats prob stretching it) http://www.vishnutuning.com/images/e...vs_reflash.jpg

That's why I was looking for input from those who have tried it. These days you pay for a lot of things with credit cards. If they didn't deliver on what they promise(d), it'd be pretty easy to dispute the charge based on that fact. That's why I would have the car dyno'd before and after (if I can find a local 4-wheel dyno).
Their claim is pretty bold. I would figure with the size of this forum, a lot of people would be interested in it the way I am, and many would have tried it, So far, I've only found a couple of guys. One had a dangerous knock count, and one apparently did not.

Just had an 03 on the dyno with a DP, high flow, stock exhaust, intake and Vishnu flash. 233 hp. Knocked something fierce. The log showed 15-20 knock and the air fuel was at its richest point 12.8, average of 13-13.5. The fuel tables were so lean as if the car had 780 injectors. This is the fourth car I have had on there with the Vishnu flash and similar results. Put in another map and got rid of all the knock and left the air fuel at a safe 11.4 for 91 octane.

i have no personal experience with mellon, but from the positively massive number of satisfied and better educated customers this guy has (as you can find pretty easily on evom), this seems the way to go. if you were east coast, i would recommend waiting till spring, as that is when local shops will have their spring open house/ dyno day, and you would save yourself a good amount of money on the dyno/tune expense. in any event, mellon seems to do the best job of continuous customer service and explaining to you what he is doing with your tune, making you a smarter consumer in the process.

i can dig up about 5 separate folks that PM'd me following my original post, wondering why my car was so "special" that it made more power than their vishnu tune and wondering if i had similar knock problems. so we don't mix things up too much,

1. 5 people isn't exactly a whole lot, to be fair. that doesn't mean, though, that every person with a vishnu tune and having problems managed to read my thread and pm me, however.
2. the guys with the vishnu mail in flash appeared to have the most counts of knock and less power (the latter of which is to be expected on a base flash with no tuning).
3. my car was dyno tuned by shiv on a dynojet. speaking with other tuners, it seems that a load bearing dyno is the preferred method over an intertia dyno.
4. for the record, shiv's tune did record about 77whp gain with just a 3" exhaust that still has a high flow cat. and at that time, no one could figure out how to gain that much power without a test pipe and a walbro fuel pump.
5. times change, and there are equally effective, and significantly cheaper, ways to go about tuning evos. the california tuners have the most experience with 91 octane, that's why it's a good idea to go to those tuners if you can find the time to get out to them. it was a while ago, but looking through the socalevo forum revealed some really surprising results despite the 91 oct.

For your car (basically stock), you absolutely don't need to dyno tune your car -- don't get me wrong it is great, but not necessary. Contact Jestr, he will have you take a few logs and then work with you to get your tune solid. My guess is you will likely gain ~45 whp (based upon my experiences). Good luck

I'll jump in on this one, seeing as I "had" a vishnu flash. I would NOT use his flash. I had way to much timing in 2 places and in those places I was getting NASTY knock counts. I also noticed that he did not adjust the low oct. & ign. map incase you do get knock. The car was also WAY to lean for 91 **** water pump fuel. It was in the 12's on the afrs. A guy with an evo 9 I know also had the same problem with a vishnu flash 5krpm to redline was up to 9 knock counts, no less than 5. As I always say he is one hell of a nice guy in person will not B.S. about that, but his evo tunes FTL. The guy has a pattern when the wrx was out he was all behind it, then the evo came out and he dropped support for the wrx. now the evo community left behind with his new toy the BMW

Tell us what mods you have or what mods you plan on having for whenever you choose to get the car tuned. As stated before, Vishnu is widely known for fairly bad tunes with high knock counts and they cost too much anyway. If your car is stock or even has all the bolt-ons, I would recommend just getting a flash through e-mail. If your not familiar with that, read up on the ecuflash section and it will quickly explain itself. In short, you won't have to send out your ecu or anything like that. Mellon is a great tuner and you can't beat the price of his tunes (like $50 or something ridiculously cheap like that). Also, Jester and TTP are also very experienced with this and you should check out their websites. All of these guys will send you a tune and then you can do a log of your car with your laptop and send it back to them and they will check it out and try to improve on it if necessary while making sure the knock count is at it's absolute minimum.

As far as getting 380 hp from a flash is concerned...yeah...ok...that's cute. There is no flash in the world that could give a stock Evo (or close to stock) 380 crank horsepower let alone 380 at the wheels. I'd say good tuners can get about 30whp out of a stock Evo on pump gas with just a reflash. Don't confuse crank hp numbers with hp to the wheels. Crank hp doesn't mean anything. All of the mods in my sig on my Evo IX are good for like 350whp. So, yeah...do the math on the bulls*** numbers that Vishnu claims they can give you.

They are primarily all about flashing the new BMW 335i's and such anyway. With those cars, they can actually gain a lot of horsepower over stock with just a flash. But that's for BMW's not Evo's.

Hate to break it to you Matt, but 270whp on a Dyno Dynamics is 380bhp on an AWD car. This would be roughly 318whp on a DynoJet.

As far as that chart is concerned, I would say it's most likely a modified Evo w/ at least exhaust. BONE stock Evos do not make 220whp on a Dyno Dynamics. My evo with catless TBE, K&N cone, MBC @ 21psi, and stock untuned ECU made 226whp on a Dyno Dynamics... so his test bed in that chart is not bone stock, merely stock ECU.

Is it a stretch? I'd say so. Is it guaranteed? I don't see how. But is it impossible?. Surely not... especially if you have an exhaust and other supporting mods.

Wow! I guess my ex evo was a Vishnu fluke.Over 30000 miles 10000 with 310-335whp depending on gas and 20000 miles with 460whp-500whp depending on gas. All that knock from the bad tune was likely the reason I rolled it. LOL! Truth be told Shiv is kinda in a different game(BMW) and there are others to get u the power u need. Go to So Cal Evo and probe. U got Alfred from TT, Scott Gay RRE, Looney Toons, etc. Alfred from tuning tech is my vote but he is a friend of mine so ima lil biased.

to the OP, let me sum up all this posts you've just read:

1. get a mellon tune, package b, or jestr M1 flash - 150$ - http://www.mellontuning.com/ or www.jestrtuning.com
2. get a perrin downpipe, highflow cat, and cat back - 1025$ - http://www.perrinperformance.com/pro...gory=6&model=3 (feel free to sub in whatever exhaust, i just like this one because it's just a hint louder than stock, i can still use my cell when cruising at 80, the high flow cat actually works as a catalytic converter, and the DP fits properly)

you've got probably 310-330 whp (dynojet) and still get to utilize stock parts that are OEM quality and your exhaust note will be buzz, rattle, and resonance free and clean for daily driving. if it's done right the first time, you may never have to mess with your car ever again.

that was my goal, and having been through 2 tune and exhaust iterations, what i suggested above is exactly what i would do now (unless a local shop had a dyno tune special) and i would have saved myself literally $900 on shiv's tune and $250 on my ebay exhaust.

the beauty, and irony, of it all is how basic tuning is so competitive nowadays that a tune is cheaper than the hardware for an exhaust.

The only difference, which is a huge difference, is you are comparing a naturally aspirated vehicle with/without vtec vs a turbo aspirated vehicle. I have yet to hear an Evo that I didn't think sounded good. Some sound different and some are louder but they don't sound like NA cars. I love my BR exhaust tone. And exhaust is a good upgrade on any turbo aspirated car. Just my 2 cents

Thanks guys... I've learned a lot. I didn't even know there was a West Coast forum. I went there, and got some leads on local tuners. I also found Works' forum and site, and have e-mailed them about their 340 kit. Having read multiple replies about the tune, I'm gonna stay away from Vishnu. Like I wrote, I want to spend most of my resources on the chassis and suspension, and just want a fair amount of reliable hp. Being a dyno owner myself (bikes), I'm still a little skeptical of mail-in flashes, as I've reworked a lot of internet maps on bikes brought to me. I guess with AWD cars, it comes down to the cost of the dyno needed, and having a choice between a mail-in or none. Then again, I spent $30k on my dyno, and $30k on the room + $10k for install. Who knows..
Anyway, thanks again for all the responses.

if i may, i recommend that you go with Motul RBF600, Ferodo DS2500 pads, rear bumpsteer kit, rear trailing arm bushings, front roll center correction kit, 0/0 toe, 2.6 f/1.6r camber.

hopefully, the folks here were able to save you some good green.

Dunno what to say. I don't have any knocking/pinging problems, though I wish more reviews were posted earlier now :-p

Haven't had time to dyno again since I've been busy at work, but I'll post something once I get a chance to schedule at EIP.
