i recently put together a t3/t4 setup and it idle perfect but once you rev it....it wants to stall or does stall when the idle come back down....also its breaking up when try to rev all the way...as of now i am running a draw thru setup with a cobra maf.... idk if the maf might be bad or the bov which is a greddy type s needs to be recirculated..... any suggestions?

yes you need to recirc your blow off valve back into your intake

Ok thanks what if I run the maf between the ic piping would I still need to recirculate

if you put the maf in the piping you would have to move the bov flange to the hot side piping also your problem sounds maf related the motor should still be able to rev freely the bov should not affect the way the motor revs yes you will run a little rich but my boy dosent have his bov recirculated and his car runs fine only stutters a little between shifts

Aight good looks I have to check to make sure there is no leaks

yea i would say check the possion of the bov

aight i have a feeling it might b the bov *** when i rev the car the bov opens and then the car stall

you need to remove one of the springs in the greddy bov to recirculate it

today i removed the big spring....i ran the maf between the ic piping and it doesnt stall anymore...so that problem solved..now when it wont rev freely it breaks up around 5-6k rpm.. i check for leaks but couldnt find any .....any suggestion?

also the boost guage is reading like 25 vaccum and when i rev it....it builds like 3-5lbs of boost which is weird *** i thought it shouldnt read any boost
