OK guys, newbie here. My wife bought a 09 H3 a few weeks ago and based off searching the Internet, went with a Air Doc intake and PCM for less to get a little extra power and to correct the speedo since it has 35" tires.
However, I have been unable to get a computer that works from them. Both pcm's they have sent me result in no start issue for the H3.
Are there any good alternatives? At this point my frustration level is so high, I just want something that will correct speedo. And no way in hell am I going to send in my OEM PCM for it to get screwed up too.

 

If it is an ALPHA, go with the BANKS AUTOMIND.

 

Sorry. Should have mentioned it's a 3.7 manual

 

Just received a call back from PCM for less. Going to look at one more thing before giving up

 

Update. Found out that i was receiving the wrong pcm from them. Correct one on the way. See if 3rd time is a charm when i get home from business travel

 

I have a Hypertech for my 3.7 .

 

flashpaq 5 truck is super fast now and shiftpoints are amazing took 5 miutes

 

Well, the 3rd computer from pcm for less didn't work.
So I will look into the flashpac and hypertech

 

Flashpaq is ONLY for 08-09 Alphas.

 

Went with the Hypertech Max Energy 2.0. Gave me the results that I was wanting. (Better low-end, midrange, and speedometer correction flexibility)
