Thinking of picking up hp tuners once I sell my car. Would be nice to make some changes to the tune to maximize the benefits of the ported manifolds, fwi, and shift kit.. I could just do a mail order from zzp or intense but that'* no fun

Yea, mail order tunes suck when your constantly making changes. Get Hptuners, I have it, it saved a lot of headaches when I did my V8 swap.

Ya my wife'* trailblazer has a tune and it'* great but I'd still like to log some run time and maximize it'* efficiency.. Also be able to have one regular tune and a 93 octane tune too with the ease of switching back and forth

You might be able to install a dual flash system in your PCM....
