i just redline first time of my Evo today..when turbo kick in.. the Evo just fly.. but when it pass around 5500rpm... it boost it kinda gone... it that normal?? i heard you can reprogram the ECU and keep the boost up til redline?? i'm newbie of my EVO ...

 

yes its normal there are many things you can do to yoru evo....just read the board

 

Afc II and boost controller me friend

 

the feeling of running into a brick wall after 5500 rpm is due to two things......you're running really rich from the factory after 5500 rpm and boost tapper from 19 to 16.5psi.

Welcome to the redline club.....kinda sucks for now but they're easy to fix.

 

I felt exactly them same about my evo. Shiv at Vishnu Xflashed my car and now the power band is nice and fat. No more "nosing over" in the higher RPM. I was amazed that this was possible with 91 octane. I'm really impressed with Shiv and what he can do. I chose this approach as to not blow my engine up with a boost controller. Nothing against the guys with boost controllers, it has to do with self controll

RonV, i got a question... does Shiv reflash on your stock ECU or you bought the plug and play set? it Shiv website price is standard to everyone.. or you can ask him for better deal? Thanks

 

Cheapest way to fix that problem is a boost controller set at 19.
