Alvin from PCMforLess is tuning the H3's now. Typically you pay a deposit for a loaner PCM (which is sent to you first) and tuning. You remove your PCM, install the loaner, and send your PCM to them to tune. Then exchange the stuff when they ship your PCM back to you.
We use the same tuning program - so they sent me one of their tunes electronically to check out. I'm going to evaluate the tune in 3 stages:
1) Look at the actual tune - what and how tables were modified,etc. - This lets you gauge how the tuner made improvments, the tuner's philospohy, etc.
2) Install the tune and run a few tanks of gas through. SOTP testing, MPG testing, etc.
3) If I have time, I'll do a before and after dyno.
I plan on posting the results here as well as how my own tune is coming along.
