still missing power after I/C replacement
just had my exhaust manifold replaced for cracks on both sides and had my i.c pump replaced and the car is faster than before but it still isnt tire shredding fast like it should be, it feels like it hesitates before it gets going too? what else could turn off the supercharger besides the i/c? i have 6k left before it needs new spark plugs but my brother has the exact same car and i can feel the difference in driving the 2 of them any ideas?

Make sure the I/C coolant system was bled properly.
If that is ruled out, you could have a plugged fuel filter/failing pumps(if they were never replaced).Also, lazy primary oxygen sensors, old spark plugs, stretched supercharger belt, worn/slipping supercharger clutch pulley. All of those could contribute to a decrease in power.

If your car has been modded for a while then you may need plugs sooner than the advised mileage. Don't forget the suggested maintenance was scheduled for a stock car.
