Bucking at 4500

[mitch1659]

when i punch it after the car hits 4000-4500rpms with no boost controller the car starts to buck do i need a bigger fuel pump or am i hitting fuel cut and wut do i get to fix the fuel cut if that is wut it is. I also just put greddy intercooler piping, greddy BOV and a intake and my check engine light come on now wut can i do to fix that .

I had my CEL checked and the code thta came up said there was and air/fuel malfunction is there sumthing i can adjust that will fix that because it has only come on since the intake and the intercooler piping.

Thanks

You always want to investigate a CEL before you haphazardly start messing with everything.

Based on what you described I'd also look for boost leaks as a source of the bucking since you just messed with the intake system.
