new car, 10 miles to gal., no power
i bought a 95 gsx with a rebuilt engine still on break in miles. After the easy miles were gone i started noticing that i was gettin 10-15 miles to the gal. I have 550's and a 255fp with no s-afc so i know i am running rich and i get a lot of black smoke. i tried reading the o2 voltage but it doesnt seem right. i tried boostin more to see a difference in power but at 15 psi it didnt really change much. i lined up with my friends non-turbo stock talon and only beat him by maybe 2 car lengths ast 90 mph.Could this just be the s-afc, what about a clogged cat? sorry for long post but ive done research and never found what i was lookin for.
