I just wanted to get a thanks to DJ and Vivian once again for there awesome tunes. I recieved a new tow tune last week (1st tow tune for me) it has a cold start issue built into it along w/ the EXHAUST BRAKE.... I didn't know it to begin with and it took me a while to figure it out... but the exhaust brake works AWESOME and I have never been happier.. The tune runs great and keeps the egts down just like I was wanting it... Thanks again for your support to the site and providing such great performance products:smoke...
