First post here. This site has been very informative for me on my decision on buying a diesel and what parts to get. First thing I ordered was the Edge Juice/Attitude combo. Was a breeze to install. Saturday, I took my first long trip down to Socal with the truck. I was towing a 6k enclosed trailer. Seemed to be allright when I didn't need to get on it. That changed when I had to pull out on Hwy 12 from Hwy 113 near Rio Vist. Treacherous intersection with an uphill climb. Truck fell flat on its face. I was running on power level 1. I pulled over in Rio Vista and unplugged the juice. The truck then ran like a [email protected] ape. No problems after disconecting. I just bought the truck a week ago as a certified GM used vehicle. It has 18,000 miles. Sorry for rambling and thank you in advance for any advice.
