Well, I am about to buy an '03 EVO - yellow with the following mods:
HKS 264i/272e cams, Buschur 3" exhaust, Buschur 440 turbo kit upgrade, UTEC piggyback computer, ACT street clutch, Walbro 255L/hr fuel pump.
My questions are these:
Do I have to get it tuned to be reliable/safe? Where in SC can I get this done? Also, what shops reflash the ecu and how much does this cost?

Also, what is the max psi I should run to keep it safe with these mods? This will be my everyday driver once I sell the Civic. I won't keep it there, just turn it up to this psi for races on weekends sometimes. It is now at 22 psi constant, is that okay?? He doesn't drive the car now, he's just holding it for me until the Vic gets sold.

Thanks for all the help, I will be posting here almost daily now that I am "approved" or whatever.

 

And just so everyone knows, I did a search and couldn't find jack that was related to my particular questions...thanks.

 

YOu have a big turbo upgrade, so most of us have no idea what your safe boost levels are. You should ask Buschur directly by giving them a call.

Yes, of course you need proper tuning in order to safely drive that car...also, to make the power it should be making, you need proper tuning. There are no flash tuners in SC...in fact, the SC guys are driving down to Atlanta for Dynoflash's tuning trip at TopSpeed. You can drive down there and get a full, custom road tune, which will cost about $399. That is my recommendation to you, because a base mail-in flash will probably not be what you want on such an extreme setup as that.

 

Sounds good, I have been wanting to to move out soon, anyway.
What about NC? I am right off I-77 and go to Charlotte often, that is why I ask. Thanks alot for the help, bro. for you

 

Was this yellow Evo you're about to purchase on Ebay from GA? It sounds like one I was thinking about buying as well...had the same mods, year, and color.

Well, good luck with it if you do end up purchasing it.

 

damn.....Vic meaning crown vic? What a change in cars and power.... Sorry for being off topic..just curious.

 

I think he means vic as in "ci-vic"

Sounds like a nice Evo but make sure and get a tune ASAP. With those mods driving without a tune is just asking for trouble.

 

Sure was, bro. I actually found it on autotrader.com and test-drove it, then found some good pics on ebay, which is linked in my sig. Anyway, the car is badass. I already put a deposit on it, and now just need to sell my Civic for a downpayment so the loan won't have to be huge, yaknow?.

 

No, dude, vic as in CiVIC. Still a big change, tho, fosho.

 

Did the prior owner have it tuned with all those upgrades? Iam sure they did, maybe they will tell you who tuned it.

 

I don't think so, but he does have a UTEC piggy-back which is supposed to help everything mesh better, but Ionno. I did drive the car, tho, and it ran fine with no CEL's or boost spikes at 22psi. It did idle a little funny, but he said that was normal for a modded EVO. Is that true, btw? I mean, do they usually have a sporadic idle?

 

Uhm, a UTEC is a tuning device, so that means it should be tuned. That's what piggybacks do...they provide a method for tuning.

No, a sporadic idle is not normal, but cams can cause you to be lopey. 264/272 shouldn't be too lopey, and proper tuning can remove it completely.

 

Wow, I know what UTEC is, dude. I also know that anyone with a labtop can use this device to tune their car with or without a dyno. Has the car been dyno-tuned? No, but the owner did look at the power curves and make adjustments to help the car run smoother. I am pretty sure the idle roughness is due to the timing of the cams. Yes, proper dyno-tuning is on my to-do list as soon as I get the car. I know that's the only real way to accomplish accurate tuning. Thanks for the input, though.

 

This car has to be tuned already. It would have broke a long time ago if it was not. But still get it checked by a pro.

 

Yeh, it's been ghetto-tuned (w/out a dyno).
Don't worry, fellas, I'm gonna take it straight to the dyno when I get it, and it'll probly see around 400hp, but we'll see.
