New H3 mods for MPG
06 H3 3.5
Just bought our first Hummer and the wife loves it. That is all that really counts. First mods for her was 2 10s in the back and a MP3 hookup to the factory radio. Now she is real happy. I'm not so happy with power and MPG so now is my turn to mod a little.
Here is my list not in any order
AirDoc and K&N Done! Nice piece.
SuperModulation throttle body, Spark upgrade with Iridium plugs.
Exhaust upgrade
Pcm forless, I did a little reading and that seems to be the ticket.

What is you guys opinion on these mods and in what order?
What kind of MPG gain do you think I will get?

I have read a lot of posts where people that had put in the Iridium plugs took them out.. I have also heard mixed reviews on the PCM for less also. Some say it helped some say they got worse afterwards.. I would like to get that also, but I dont want to spend money to lose money... For ones it has worked on I heard the tow setting is best overall.. Good luck, I am anxious to see what happens with yours.

I would mate your SuperMod Super Sparkz with OEM AC Delco plugs. Super Sparkz may not net you anything other than perhaps a cleaner burn?
Also consider the SuperMod or PCMforless Efan conversion. I am very pleased with the PCMforless Efan, working perfectly for a year now.
You've got the best stuff listed otherwise.

I have an 06 H3 3.5L and I just completed the Air Doc Intake and installed a $26 Spectre air filter. Seems to work perfectly, and mpg has improved. Really noticed the improvement in the passing lane. I got a couple of mpg, or more, according to OBDwiz. Only time will tell what the actual increase will be. Good luck with it.
