I'm about to start playing with this Trailblazer but I was wondering if someone had something they are happy with to get me started. I do a lot of city stop and go and a fair share of tollway driving. Im really looking for a mileage tune especially in the 70-73mph range. The truck is stock with 46k miles. Thanx Gary.
Replied to your PM.
This goes for anyone with a P10, I have a free basic tune that does all the simple things. No TM, reduce shift times, remove PE delay, etc but it does NOT have tweaked VE tables and spark is bumped slightly over all RPMs. Basically its a rough starter tune, make sure you log the heck out of it and make adjustments accordingly.
