Thats the problem right there, Some cars seem to be more sensitive than others when it comes to venting to atmosphere. Get a PFC or standalone and you won't have that problem anymore. Or you could just put the stock back on an reroute it back into the take like it is stock.

Hey do you think that maybe its a loose wire.Cause when your stopping everythings abruptly moving towards the front and at a speed bump everything is getting shaken up.

But while driving its smoothly moving.

How far are you from Broward??Seems like there's a couple of RB's aroung SFL huh.

THe custom piping prevents me from going back to stock, my friend is telling me that i might less'n the effect of the different set up by putting the MAf between the BOV and the Throttle body that way it gets a more acurrate reading of the air in the piping...all the wires are tight and i'm in homestead bout 40 mins from broward

what?

everything that controls the car is bolted down, none of it moves with you hit the brakes.

do *NOT* do a blow through MAF without retuning your car. moving the mass airflow sensor is not a game and can cause serious engine damage if done improperly.

you need to recirculate your BOV to eliminate this problem.
