Hp tuners with hypertech
Basically my laptop has become unreliable, so I'm kicking around picking up a used handheld to take to the track for shift point and tire height adjustments. Just wondering if the handheld would possibly screw up my tune in the process.
You can modify the existing tune for WOT fuel, WOT spark, shift points, shift firmness, idle speed, tire size/gear ratio, and more
