Hello, I am new to HP Tuners. My daughter bought this 1999 Chevy Silverado 4x4 about a month ago for $500. The reason it was so cheap is because someone had tried to steal it by popping the steering column which in turn set the security vats off. The owner had someone try to fix it which he didn't know what he was doing so she gave up and sold the truck to my daughter. Yea my daughter thought hey dad can fix it for me! Well after finding out what version OS it had which is not a popular one(OS9379910) I was able to flash it to OS12208322 using PCMHAMMER and was able to disable the Vats in Tunerpro. After messing with that for a week I finally got the truck started but cannot get it to run right. I ended up breaking down and bought HpTuners which has helped a lot with it running better but not all the way. It starts up and idles perfect but when you put it in gear to take of it bogs down really bad. It was throwing a code of P0355 coil pack. I replaced #5 coil pack and now it is throwing P0353 which is odd and it doesnt run any different. If anyone has any ideas I would sure appreciate it. My son in laws truck broke down last week and he is using my truck until I get it fixed. SO now I have 2 trucks down. Any help would be appreciated. I am including the scanner log if anyone can look at it and help me out.
Also I have changed all the values to the 1999 Chevy in the new os I flashed to it.
