Last month I did heads and cam on my car and got it to run real good, this last weekend i put 24's , a new MAF and a edlebrock intake manifold on the car, Now the cars bogs down and backfires when i mash on it. I never touched the distributor so i dont think its the timing. I thought it was a vaccum leak so i hooked up a vaccum gauge, it reads about 7 or 8 which is really low but i know the cam lowers it just dont know ho much. I can sneak up to high RPM's at quater to half but at wide open shes says no. Thanxs

it runs perfect at quarter and even up to half throttle

the cam is a stage one trick flow

check out your TPS.

what mass air meter are you using?
if it has the sample tubes make sure the small side faces the filter.

when I got mine it already had the tube attached and they put it in backwards, so my car ran, but like crap.
really rich, and popping, bogging, and it just lacked power.
changed it around and it ran strong as ever.

when when u say small do u mean in diameter or lenght, the short lager diameter is facing the filter and the smaller longer side to the throttle body

what psi do you have the fuel pressure at? you need to check the timing bc of the new cam you have in there

rustynotch

the cam was done a month ago and the timing was set then, im still waiting on th regulator, do you think i could be hitting some sort of fuel cut off

stanglx2002

its either to much fuel and your flooding the engine or the timing is off i would still check the timing just to make sure

tomabram

i agree, check the timing.

you got it on backwards.
make the smaller diameter face the filter. you will notice a crazy difference.
I had the same problem when I first got my maf.

the plug for the madf should face toward the passenger fender
