2003 MSP Spicey Orange
Hey I recently installed MBC and Fpr from Joe P into an unflashed 2003 MSP I have Injen CAI and boost guage and A/F guage. Car ran unbelievable for about 2 days today I was getting bucking almost or like fuel cut bad at about 10 pound boost in 3rd , 4th and 5th gear around 3500-4000 rpm came home turned down boost to 8psi and its gone I want to be able to run 10-12psi but cant due to bucking HELP PLEASE:cool: :rolleyes:
 
Haha....that is def. fuel cut.
Wait till it gets really cold, you won't be able to run 8psi without bucking.
-buy an fcd and it goes buh bye.
 
You need the FCD (Fuel Cut Defenser). It was probably cooler out today than the past few days....cooler air is more dense, and the MAF will max out at a lower amount of boost.
 
Hey read the thread I started earlier, basically about the same thing. Some of the guys have explained it pretty well on there. good luck.
