Ok, here goes...
99 Cam z-28 a4, slp longtubes, slp cats, slp loudmouth, granatelli lid, stock maf w/ported housing, tb bypass, k&n, everything else is stock..
ok, when i purchased my car, it had hypertech on it, i "deprogrammed" my car, however i think it leaves stuff in there.. who knows. anyway, I dont know if i have a real "stock" bin so if anyone has a 99 ss or z-28 lemme know.. i need your maps. However, when i log my LTFTs they are between +9 and +21.. they jump all over the place.. if i average them its like +17 or +18.. all over the map. Anyone have any clue what could be causing this?? Is it my o2s, vacuum leak, who knows??? i can send anyone a log file so you can see if you dont understand what i am trying to say. I dont know if its just the old tuning or a physical problem w/ my motor.. plz help. I cant tune unless i figure it out....
