Over 9000 miles on Livernois tunes here. Zero probs. Ive run the 93 @ the track for the majority of those miles. Ive also run the 87 tow and am currently running 87 performance.

i just downloaded the 93 tune and installed it...i was running the 87 performance tune..will let you guys know if i can tell much of a difference. i do know that i paid about 8 bucks more today to feel it up with premium..

Thats not to bad. If you fill up twice a month that's less than 200 more a year.

I've been running the 87 tow tune using 91 octane for the past 3 weeks. All I can say is WOW!!! We recently purchased a 30' travel trailer, and my truck pulls it easily. I have yet to go past half throttle while towing, and that includes going up some fairly steep grades.

While not towing, the tune is still excellent. My favorite tune is still the 89. Once I can fit both files on the AIW tuner, I'll be a very happy camper.

Livernois, you guys rock!!

yeah..thats about how much i fill up..sometimes 3 times a month. will see the performance diff..im sure MPG wont be any better since i will probably be a little heavy on the pedal..

Almost forgot... The 87 tow tune netted me 21.2 MPG from LA to Vegas (not towing of course), on 33" tires. Used less than a half tank of gas.

does anyone know that when you download a tune file off internet onto the tuner does it overwrite the previous tune? i hope it didnt mess with my stock tune file. ive notice when i install the tune on my truck, it never says if its the stock tune or the new tune.

It overwrites the special tune only. To reload a stock file, just tune the truck again without downloading another file..

Thanks..

One more ? JC. Sorry to bother you. I have 87 installed in truck now. When I email Rick and download the 93 onto the device and then plug the device into the truck is it going to install the 93 automatically, reinstall stock, or give me option of what I want to do. Only reason I ask is because instructions said something to the effect that the device will install whichever tune isn't on the truck at the time. So I thought it might want to reinstall the stock instead of switching to the 93. Thanks
