i drive an evo 8 with just a few basic mods. ive got aem intake, greddy bov, 3" cat-back, turbo xs utec, walbro 255lph and 720cc injectors. im havin a problem with my throttle response and acceleration. when i push the gas im not goin anywhere. i used to have an afc2 and once i put it in there it screwed it up for me. the knock function never monitored right and i couldnt ever adjust the knock. if im drivin down the road and hit a bump the throttle is touchy. do you think my timing is off or maybe a bad knock sensor??? somebody help im gettin frustrated. thanks guys

 

Go to Someone Who Can Tune the Car, Youo need a Custom TUNE. Thats All

 

You have 720cc injectors with the mods you listed? Why? They're not needed with those mods, and they can only add complication to diagnose your problem. You have a UTEC and SAFC2? Which one are you tuning with? Who did the UTEC tuning?

I'd suggest taking to a tuner who does it for a living and see what they can diagnose. Having a UTEC and AFC is duplication of effort, and they may be fighting each other.
