Has anyone had great success adjusting there modified paramaters. Not sure how to get the most out of my 2008 Dodge HEMI U7137. Please send me your specs so I can adjust mine right. My only upgrades are CAI and true duals.

Guys I feel your pain. I had the same problems with mine. Replaced my tuner 2 times, but the 3rd was the charm. Thanks to Vas from tech support. He's the man to talk too. Very helpful and patience. The other guys need to take notice.

While installing my U7137 for my dodge ram,a error popped up. "PCM error unlock to refresh". Please help. What do I do
