ok, guys my boost pattern is 11-10-14, and the primary is not pulling like it should! The gauge shows that the boost is there, but the car doesnt pull until the 4500 rpm transition, and then it is spiking to 14 lbs. Any suggestions?????????

 

What kind of mod do you have?

overboosting is usual when you have a open exhasut, intake with no Ecu, if that the case you need get a new Ecu. The only way around that problem is to buy a boost controller, or make the "home Depo" version...

 

i have the m2 ecu downpipe, pineapple motor, greddy exhaust, flowed and matched injectors, new oil injectors, and a **** load more, but i do i have the m2 ecu, which has always worked fine....
