[MOFU]

i got my detonation problem resolved, but now at high rpm's starting from about 3500+ it seems like she boggs alot, like there's not a lot of air just fuel...the odd times i see a cloud of black smoke come out the rear end...

here's my setup if it will help ya'll genius's

30# ford racing injectors
75mm MAF sensor calibrated
mac shorty headers equal lenghts
flow master exhaust
373 gears
vortec supercharger s-trim...

i'm missing a few like suspension and all...but that has nothing do with this problem...thanks

Im guessing but, Id say you need 24lb. injectors with just 75mm MAF. Black smoke means there is too much fuel and its not getting burned or a lot of carbon buildup.

i was thinking maybe one of the cats are clogged. could that also be the problem?

[Sliepnir16]

I don't know. I figured with your mods youd be running offroad exhaust. Usually the cats overheat when they are clogged and turn cherry red. Im not sure if it would smoke with clogged cats.

Is everything tuned?

have you tried to clean the mass air sensor? contact cleaner or carb cleaner works good
