Hey guys fairly new to tuning with the Delta Force Commando setup. Car is fairly stock for the most part
1996 GT 4.6 ( 5spd ) - PI Intake Swap w/aftermarket elbow. BBK Catted X Pipe and Mac 2.5" Cat Back and 4.30gears w/drag radials.
So far with just minor adjustments through the Special Forces software we have made some real good progress at the drag strip. My question is now that I have the RECON Data Logging hooked up as I look over some data from a test pass my short term fuel trims are in the 50-55 range across all throttle ranges.
At low RPM it is reading 22-26 degrees of timing and high rpm it drops down as low as 10. MAF Voltage is in a steady range around 1.25 and TPS Volts around .94
Tried adjusting to correct the fuel trim lower as I had read online to where it should be around 10%. Made a small adjustment to the injector slope and it brought the reading to 25 but car definitely did not like it.
Hoping there is something I don't know or I am overlooking. Thanks for your help in advance, Matt
