Clear Lake, IA | Ran there tunes on two V10’s and one 5.0. I dont think it does all that much for the motor, but it really makes the transmission better. I tend to run a little over stock on tires and the drivability was substantially better then stock. I would highly recommend there tunes, all the Motorhome guys run them. Word on the forums as of lately is there customer service has been very poor during this COVID bull****. I had great customer service from them, no complaints as far as that goes. I ran mine with a TS Livewire, programmer/gauge. I did run some of the canned tunes the Livewire came with and was no where near the Five Star Tunes. | |
