Evo was running fine got it tuned with boost controller new sparks and flash ecu...
now boost breaking up and the check engine light is on I didnt even push the car...anyone can tell me why the boost breaking up?

 

Are you dealing w/a possible boost leak. Have you checked all the pipe connections?

Lets see what that CEL code is. That will certainly help.

Do you have the means to log a run & post up the results?

Just my .02

 

What i think it is it might be the spark plugs...common problem plus the ****ty tune

 

I fixed the problem it was the fuel pump and i had to regap the plugs.

 

Well, that is good news. Thanks for letting us know

 

hey on the other note im trying to make 480whp any input to get me started?

 

We'll need more info on what you have on your car and what fuel is available to you (E85?).
