If you are running at stock fuel pressure, 2/3's of what it should at for the blower, and the car is tuned to be running a supercharger, besides this being HORRIBLE for the car, is it also losing a lot of power?

This my roommates 99 Tahoe BTW.

To give an example of power loss, he only put a legnth on a stock 5.3l, 4 door tahoe to 80 mph, drivers equal and both autos. Pretty sure a 2 door, vorteced 5.7 should be a lil faster than that. Thanks a lot for the help guys. :coolman:
