Tow Tune for 2008 Tahoe 5.3

[heyopey]

Hi Guys,
i am new to the forum and new to vehicle tuning.
I just got my InTune I3 and changed the DOD and speed limiter. (worked great)

Also i am sometimes towing a 8500LBS camper.
A good speed fuel Ratio is at about 65mph. The problem with that speed is, it keeps on shifting.
can i get a tune or some advice from you guys how i approach/change this?

Thanks in advance

you'd need to get a custom tune done... www.diablewtune.com - and I can definitely get you hooked up.. I've done thousands of those trucks...

Please send me an email at -- diablo DOT help AT gmail DOT com -- with the year, model, engine of your GM vehicle, any mods done to it, what octane gas you use, which diablo tool you have, etc.. and I can send you a loooong email with info about the custom tuning, the process, etc. Thanks! -Lew
