Once a conclusion is reached, I'll be happy to disclose whatever I know. Until then, the investigation continues. Don't worry... everyone involved is on the side of the consumer

If there is indeed a problem, Mitsu better offer to either buy back the cars or give an extended warranty after they fix what's wrong.

I'm looking for a few significant mods I can do to my car, but I'm not interested in a shotgun approach or just bolting on crap for the hell of it. Frankly, what turns me off the most is what they seem to sell the most: flash, trash, blinkig lights and such..... Good grief, I wish they made stuff that would fit in unobtrusively and not too visibly. I prefer the clean and stealth type of mod. I don't want to call attention to the car of thieves, cops or ovezelaous techs at the dealer

is being consulted and hopefully they are assisting.

PS. A/F is off-the-screen rich by 5600rpm so there's not much to look at. The extra fueling is critical for adequate knock surpression/charge cooling.

Since the fuel is there for knock suppression and charge cooling, wouldn't it be possible say, to install a water/meth injection kit to do the same function, so that you could lean the fuel out more, while retaining safety?
I imagine emissions, fuel economy and smoother power delivery would be some benefits of doing so.

Yep, that's the whole idea behind water injection. I've seen it used in some good applications with good success. I've also seen it used as a big fat band-aid in order to keep a poorly tuned motor from detting to death. We're testing a system right now. May have some merit for a car running so much boost on pump gas.

Tuning sounds like it going well.
I'll do minimal mods cause to me the EVO runs pretty well and fast enough.
More than anything, I'm more impressed with it's handling and braking and its ride over bumpy roads and those awesome seats.
But, I am concerned about something. I'm about to buy an EVO but those dyno numbers don't look promising. If 180hp to the wheels is true in stock form, then this car is suffering a 33% driveline loss. That is unheard of even for an AWD.
Either there is something wrong with the dyno or testing method or Mits is bringing and selling a product that is not living up to it's marketing and promise. Truth in advertising is important.
As much as I like handling and all around competence in a car, I still expect to get the power I'm paying for.
In this whole thread this hasn't been brought up. Am I wrong in my thinking? Is so, why, can someone explain why there is such low power output from a supposed 271hp engine?

Hey Heff, if you have something intelligent to offer then offer it.
If you don't then don't. I know my way around the internet very well thank you and don't need your simplistic advice.
If you can't answer the question, then don't say anything.
As far as being a "noob", I've been into cars for a long while now.
I don't think I qualify for "noob" status, but thanks for considering me anyway.

Hi,
There was several threads and a "lively" (as in war) discussion of this last month. The summary is:
The only valid dyno numbers for different cars are from the SAME dyno and Vishnu has numbers to show lower than expected DIFFERENCES between an EVO VIII and EVO VII and a WRX. Almost all of that difference was accounted for because of the California 91 Octane gas (180whp). There are still some unexplained differences which are being discussed with Mitsy. The rest of the country is seeing close to the advertised 271hp, as stated on Vishnu's website.
If you are in California, then you need to consider the decrease in performance resulting from 91 octane. If not, then knock simply is not an issue with 93 octane gas and stock boost pressure. The cars are very quick and at or above the 271hp stock as advertised.
Hope this helps...

Not to keep this going, but how much driveline loss is there in the EVO, percentage? We have 93 available all the time.

My rear wheel drive car, on a CHASIS dyno, recorded a loss of 17%. As if any AWD drive car on a WHEEL dyno, is going to record 15%

I believe that the "urban legend" caveat on the 15% speaks for itself. 23-28% is a reasonable estimate for AWD. What's the beef?

Ah, okay...
I thought urban legend meant "something that has some element of truth behind it, but nobody can prove whether it's true or not"...
Kinda like the the urban legend about crocodiles in the sewers...
