Hey guys, I'm back in another lightning after selling my old one about a year ago. I didn't post much, so most of you probably don't remember me. Here's a pic of the new one I just got.
The truck is pretty mint, and has only minimal mods such as a K&N intake and it has been chipped. Unfortunately, the owner wasn't sure what type of chip it is, as it was done a long time ago. I'm having a slight issue with it. Anywhere up to about 3/4 throttle, things are fine. Boost builds, the truck accelerates normally. However, if I hammer down, and go WOT, the truck falls on its face.
At WOT, the RPMs build to about 4000 normally, and then they kinda stop building, truck is shuddering, the boost gauge falls to 0, and the supercharger SCREAMS. I let off pretty quick after all this starts happening. Any ideas?
