OK seriously if you have a strong running car just don't waste your money on stupid programmers. Since I been messing with this Diablo tuner last 2 months I have been chasing ET that I know my car should be running. The performance tune(yah right) I have tried all grades of pump gas removing timing needed for each grade with little to no luck. Car has always ran its quickest on 87 octane.
Of late I was beginning to wonder is clutch going out and slipping at track? last weekend I took 4* initial timing out of my Steeda timing adjuster setting it back to factory 10*. Car loses 2 tenths. Add timing back in and it picks back up. Ok thats not the issue.
Today I decide to run 93 Sunoco. I know the car is a hair slower on it but I wanted to make sure I wasn't having motor issues after Wednesday TNT where it was smacking rev limiter on the drag radials and acting all kinds of weird at top end. So I start today with a 13.05@103.90, got to be kidding me and I really begin to question my clutch. Next pass I play with adjuster and couldn't hit the 2-3 shift. Pissed I mess with adjuster and something clicks in my head to put stock tune back in. First round not knowing what to dial I put up the 13.05 but I red lite and run it out and it goes 12.73@104.97 then in the 2nd Chance race it goes a 12.74@104.70 and lastly a 12.73@105.39
Car would have run mid 12.6's on 87 which is where it should be running this time of year.
Time to get a new speed cal to correct speedometer issues since I can't use tuner to correct. Man I so love my $360 code reader/paperweight
