Long term fuel issue

I know alot of you guy's don't really work on the cougar's/t-birds but I figured I'd ask here see what someof you know.


I got a 97 cougar, True Duals W/ Flowmaters/ Underdrive Pullies/ Cold Air Induction with custom air box/Cross Drilled Rotors/Shorty Headers/ P&P PI heads/ PI intake/ crower stage 1 cams/ Trac lok 3.73:1 gears/ Block bored 30 over/ Forged crank/ Mahley rod's/ Diamond flat top piston's/ nos kit w/ 100shot and compucar purge/ Dual oil Filter relocator w/ oil cooler/ Trans cooler/ Trans shift kit/ Marauder T/C/ 255lph fuel pump/ and 30lb injectors.

Now the problem im running into right now is the long term fuel trim is off i checked it last week and read -15% bank 1 and 2% bank 2. I swapped injectors side to side, to see if the problem folled to see if injectors are goofed but came up with the numbers -23% bank1 and -12% bank 2. (I will double check the nubers when I get into the car i wrote them down but I got a bad memory) Short term fuel trim is fine, o2's are fine, compression is fine, What could be the problem?? Now I did a KOER test with the otc scanner at Feinn Tire and now I'm bouncing off the rev limiter when in 2nd gear???

The guy that tuned my car is coming over Monday to see what we can figure out. He doesn't think it's in the computer but then he told me the other day that I could have lost one of the adaptive tables.

Any suggestions on what this could be would be greatly appreciated!!!
