Someone has another post about the differences between the 3.5 vs the 3.7 and how much of an improvement we can get out of getting the 07 tuned. If you get a chance Kelly or Alvin could you post a quick answer to that post purtty please? Any improvement is pretty much worth it to me in the long run. Here is the topic: https://www.hummerforums.com/m_56385/tm.htm

 

Give her a call Luke..She or Alvin maybe too busy right now tuning all the orders to get back here...

 

Very true will do after lunch. Thanks Dennis.

 

Is this list closed or still open? I would like to jump in on a discounted one myself...

 

I would like to know to if still open I'll get one today

 

I would also be very interested. How about another group buy for us new H3 owners?? Thanks, Tony

 

Better just call Kelly and plead your case..Maybe a while before she checks in here.
