MotorOps EFILive Single 2007.5-2010 LMM Tune

Nice upgrade!

LMM drives better. I have the single heavy tow tune which exhaust brakes with tow haul active or inactive (no exhaust brake switch on LMM). Power feels strong through the RPM range but I think you could get a few more MPG with a different tune (for obvious reasons). Makes me think an upgrade to the DSP5 package might be in my future! I appreciated how easy Tune Supply Shop was to work with, I brought my own AutoCal and they kept the process strait forward!

Highest quality tuning on the market!

I have used motor ops for over 10 years now on my personal and many other trucks. Not once have I had an issue. Going through tune supply has just added a second set of unmatched customer service and support. Keep up the good work!
