Upgraded Turbo and manifolds, now car bogs and hesitates throughout rpms.

I just installed a the gt2540r turbo with titanium manifolds. Now as Im driving the car hesitates and bogs throughout rpms in between 2 and 3000. Any help would greatly be appreciated. Thanks

Sounds like MAFS. How much boost are you running?

[astigsmo]

I dont have my boost gauge installed yet but im pretty sure im running stock boost. What could be wrong with the mafs?

[zach-Ka]

If the ECU is not getting signal from the MAFS it will put the ECU into fail safe mode. (Fail safe mode: Rev limiter set to 2500 rpms, runs rich)

Check your ECU for codes.

Anyway to know if its actually the mafs? So im guessing id have to get a new mafs?

[astigsmo]

So im guessing i gotta take it to a shop for that kind of equipment that checks for ECU codes?
