Hey, I didn't say I gained jack. I'm reading reviews and forums. see vishnu evo x on edmunds for ecu specs or go to http://www.vishnutuning.com/evo.htm
to see what they've done with the previous evos. Keep in mind their numbers are based off of hp at the wheels. for intake info look around. I never claimed that this was accurate, its only what I've read and seen on the dyno graphs posted on other sites. My point is that doing exhaust can get you 60-70awhp, if you go from the turbo back, and in conjunction with other upgrades, (that is you've already done the intake side, dynoed, got results, upgraded exhaust, dynoed again, and recorded difference), you can gain big numbers. The high number their is with a test pipe in place of the cat. The low number is with high flow cat. Air intake alone can net you a gain of 15-20 awhp, and intercooler pipe claims range from 10-15 awhp. I'm sure these are when used in conjunction you may see a gain of 25-30awhp. So, we're right back to the 100 awhp gains from bolt on. And Vishnu has always gained b/w 75-100 hp with just ECU.
And about the warranty, I said i didn't know, I've heard conflicting statements, but the service and parts department leads told me at the Mitsu dealership, that I could change the pipes that i mentioned above without worry. Maybe they meant they wouldn't report it for that, idk. And i did say that I've also heard that if you modify the hp at all, you've voided the drivetrain warranty.
What is your problem with what I posted, or did you read it prior to going off?
