Any experience?
A local guy has been doing some trucks and says it really helping and you can notice the difference right away.
He says he can tune my truck sometime.

Yes, I have it. I have been playing with it a lot this weekend also. I tuned a 2003 GMC Sierra with a 5.3 yesterday and it made a HUGE difference. I have to tune 3 H2's and a Silverado SS today. I'll be back in St Louis this week and should be available one evening. I have a bunch of H2's and Silverado SS's to do there, too so one or 2 nights may be pretty full.
Good news is I have some really good tunes for these trucks already! We were looking at real time data and it looks like everything is nearly dead on. I set up the 2003 GMC Sierra to tow in normal mode then when you put it in tow/HAUL mode, it HAULS. It is shifting at about 5800 rpms at WOT and pulls like crazy the whole way.

Hmmmm. I don't see where they have a tuner available for the late model gm trucks yet. They tend to run several years behind the current models according to their web sight.
