holy shit dude check out how much HP/Torque Im making at 4K vs your chart at 4K
I wonder why that is? on paper if you are running more fuel pressure it should be about the same if not better... weird...
what size ehxuast/DP are you running? I have a fmax kit so Im guessing we both have a very close setup to each other
do you still have the stock Fmax downpipe? if so thats your problem the thing goes down to like 2" at the flange where it meets up with the cat
