Accelerate

actually, seeing how you have 4-1 headers, a low restriction cat, and a cat back system...that could be a main problem....you have extremely little back pressure...this means thats itll take a little time for your car to accelerate up to high rpms, but once you get too higher speeds, youll have higher HP meaning better pick-up....so highway speeding shouldnt be a problem for you, more like just a 1/4 mi start....i suggest SC'ing your car....then thatll put your low restriction exhaust to work..............that might just be your problem (no low end power means no real torque)

i just learned of this idea a few weeks ago, so someone correct me if im STILL just talking out of my ass

but supercharging the thing would still be pretty cool, heh
