Which H3 are you asking about? It makes a difference based upon motors and years. Sending in you PCM is most certainly an option, PCMofNC offers a loaner program. You swap in the loaner, send yours in, then swap out the loaner with your tuned PCM and mail back the loaner.

2010 Alpha can't use a handheld.

Good point, changing mail in ain't easy.

I corrected my last post to 2010 Alpha as the LH9 has no handhelds that I know of. I think the 2010 3.7L can use a hyper hypertech.

Talk to the folks at BANKS. I'm using the Automind # 66112 with the SPORT 87 program for my CE (obviously a 2009 5.3) and I am totally satisfied.
Good luck whatever you do!

Better mileage with slight performance enhancement with the ECONOMY tune.

Worse mileage with significant performance improvement with the 87 SPORT tune. Great throttle response! Last tank was 13.3 with all city driving at a little over 700 ft. elevation.
