I've got about a month old PPE Standard Xcelerator Tuner for my '06 LBZ Duramax, and I've had it on the 90hp tune since I bought it. Today I installed an EGR delete kit on it, and the truck ran fine. Now I went to install the 160 tune on it (doing the exact same thing I did before) and it went through all the screens fine, but has been on the final screen ("Installing Your Selected Tuning DO NOT DisturbEE") for over an hour. What is wrong, it didn't take but 5 minutes back when I put the 90hp tune on it? Can I unplug it and restart the tuning process? Please Help! Thanks!
