I'm having issues recently of my truck going into limp mode. I have a 416 stroker. With NW 102mm throttle body and the x link adapter. I've checked wires and none have any resistance or breaks. Could it be my tac module?

 

Could be the TAC module. What year is your vehicle specifically? GM had issues with that code popping up on certain years. Sometimes its the pigtail going in, but you checked it. If you don't mind, what kind of HP are you putting down with that stroker?

 

It's an 04 and yea I've replaced/checked all the wiring and its alright I just replaced the TB and gonna see if that will fix it. My last one, the butterfly was rubbing/grinding into the throttle body itself. And right now it's at 986rwhp at 15 psi. I have a 96mm borgwarner turbo. Holley intake, fully forged bottom end. LSX block. Callie's dragon slayer crank and ultra billet rods. Wiseco pistons and prc heads with a custom grind cam shaft. I maxed my injectors and fuel pump out so I have to get new injectors and fuel pump and bigger exhaust. It's a beast that's for sure!
