I have 2001 Bullitt with vortec supercharger. The car has been dyno tunned and is running very well, but in 5th gear @ 19,000 rpms 59 mph & 22,000 rpms 62 mph I get a little hesitation. Do I have a bad
fuel pump? Or is something else wrong? Problem did not start until after car was dyno tuned. I"m tired of taking car to my mechanic.
Its starting to cost me to much. "Help"
