I have a t3 turbo installed on my wifes 07 hummer h3 with 3.7l engine. I am having trouble finding someone that can tune the pcm. Please help thanks

 

PCM of NC

 

PCM of NC can do it, get the live data logging to provide them the feedback on the tun. There may be someone local to you, check Craigslist as there might be someone local to you advertising tuning. Plenty of folks running around trying to recoup the money they spent on a tuner that could help you out.

 

I ended up using a company called lime-swap.com. The guys name is Jeremy super nice guy and he did a good job on the tune. started right up and it runs ten times better. The only problem is it runs a little lean sometimes and throughs a misfire code. Not sure if its the tune or fuel pump issues. only does it when i mash the peddle at a full stop and not all the time. Only running 5 pounds of boost.
