My car was dyno tuned with HP Tuners and now I want to adjust the tire size. Will my U7198 "see" the current tune as the stock tune and let me adjust the tire size. I do not want to lose current tune. U7198 was originally used on this car but I returned to stock before HP Tuners tune.

Re: U7198 adjustment on HP Tuners tune
Just installed Predator U7198...Performance tune...following is a list of LTFT Bank 1 and 2...
couldn't keep a steady 55mph......somewhere between 55-70 in a 25 minute hwy run.
Bank 1 averages: 0.00 -1.56 -0.78 +1.56 -0.78 0.00 +2.34 -1.56 -3.91 -3.12 -2.34 0.00 +3.12 +2.34 +1.56 -0.78 +4.69 0.00 +3.91
Bank 2 averages: 0.00 -1.56 -3.91 -0.78 -3.12 -2.34 0.00 +3.91 +0.78 +2.34 +3.12 0.00 +3.12 +3.12 etc
Real time data was 83% ...final LTFT were +4.69 and + 3.91 before I parked and unplugged it.
Average spark advance was anywhere from 19 to 40.50
Now...this is with the Diablo Performance tune.....any suggestions if I need to adjust any parameters?
Thanks everyone

Re: U7198 adjustment on HP Tuners tune
You put in a tune with the predator after getting a custom hp tuners tune? Probably not a good idea. It's probably adding fuel and timing on top of your custom tune. If you want to change for tire size I would remove the predator tune you just put in and install the modified stock tune to adjust tire size and that's it.
