tune and datalog attached.
2000 gmc sierra 1500, firmed up trans and tcc, disabled egr diagnostics, did away with egr codes, zeroed out the egr spark table adder, added 1 degree of timing, and unplugged egr valve until blockoff plate comes in. (Per customer request, I will be installing that to so they said keep it and drive it)
LTFT are 0-1, STFT are 1-3, no KR, gas mileage seems way down, could just be me. truck runs out fine, and has plenty of power. just seems like its drinking gas now. I've driven it around 50 miles and just about can watch the hand move. let me know what y'all think. Thanks.
