Friend of mine put down 460/1160 at the wheels with a HX35/40, intake, exhaust, Dragon Fire Extreme VP44, .093 injector lines and connecting tubes, 250hp sticks, Air Dog 150 and clutch. He has an Edge Drag Comp on it, but he popped a 10 amp fuse and replaced it with a 25 amp fuse and burned out the chip. It made within 5 horsepower of itself with the chip off or on level 1 or on level 5. He's in the process of building the head and saving for an S475 to put under it.
