AFter fmic and bc install, big stumble/hesitation in 5th plz help!!!

[StreakinOraNgeX]

It seems that when I put in my mbc set at around 10 psi, I feel a really apparent "thud" or stumble driving on the freeway accelerating. It has happened like 3-5 times and for sure, two times I Had more then two people in the car.I'm really paranoid so whenever that would happen I would baby it on the freeway. Any damn clue what the hell this is. I'm pretty sure it's from the upped boost. It feels like one big stumble coming from the engine. Any ideas, need help now!!!!!!!

fuel cut, turn down the boost till it goes away or get a fuel cut defender.

Are u sure it's fuel cut, it is one distinct thud and the car doesn't drop rpms...or for fuel cut it doensn't have to drop rpms?

 

[Notorious]

rpms don't drop because your car should still be in gear. Its similar to hitting a wall. Just to be sure turn down the boost and drive around for a while. If it goes away its probably fuel cut, if not then its gotta be something else.

 

[StreakinOraNgeX]

Similar to hitting a wall? maybe, but is the fuel cut a really apparent violent thrash or can it be more subtle..

 

[Notorious]

it seems to vary, on my friends car it just kind of like thuds and then power comes back on. On my car it feels like you just hit a curb.

 

[StreakinOraNgeX]

what do you mean power comes back on? I don't really no because once I felt the thud I would immediately let off accelerator

 

[grcuadros]

thats the fuel cut. happens to me when i turn it up to 9 or 9.5. at first when i hit it i was worried too. just turn down the boost a little bit.
