Can not say enough about my PCMforless purchase. Excellent service but more importantly what an unbelievable product.:woohoo:

Totally made my VOY-XL a different truck. Downshifts are amazing and the truck pulls way stronger. Before the PCM I wondered if I should have waited for a V8, after the PCM I wonder why anyone would think they need a V8 over the I6. Really makes me wonder what GM was thinking when they made the stock PCM program. :duh:

This is by far the best mod I have done to any car I have ever owned. :thx

I had a bad 2-3 shift that the dealer said was not a problem. I was having a 500 rpm flare during the 2-3 shift. This totally took care of it. The performance and feel of the truck was a total bonus. Have not had enough time to see what gas mileage does, but seems like mpg on the dash while cruising seems slightly better.
