What’s up guys maybe some can help me. Ok for starters I have an evo 8 with all the blot on and a walboro fuel pump and a tune done by Dyno Al In CT now about 6 months ago I changed my clutch and when I got the car back my profec B boost controller reset so one of my boys set it to 50% and 10 as the gain and the car ran great now about a week ago the only when I boosted the car started to bog out but if I gave gas it full boosted but it runs real bad and can boost or the problem comes back then when I shut the car off it goes away. And the engine light when on and it says multiple cylinder misfires. Now this is what I did in order so far changed the plugs changed both coils did a compression check ever thing is new and the problem is still there what the hell do I do I call AL and he told me to just bring it in and he would see what’s wring with it but I don’t want to just spend money for nothing if its something simple now one of my other friends said that the tune could go bad is that possible and would that not mean he retunes for free I have no idea any help would be great thx

 

The tune did not go bad something is wrong,boost leak,mass air sensor,gaps on the plugs something,i cant really help me because what ever you wrote hurt my head...

 

Well its def not a boost leak i can peak and hold def not the plugs cuz they were changed and you dont gap platium mass air i did not check cuz a code did not pop for it and the problem comes and goes

You should not be running platinum plugs in you EVO.

Irridium or Copper

What PSI is the car boosting. Fuel Cut?

 

^ +1 on plugs

Is that the only code you get when the engine light comes on? Doesn't give you any specific cylinder(s)?
