I have a 06 lbz with gutted cat, straight exhaust and stock filter. I have been running a edge cts and just set it back to stock yesterday, now I'm getting the p-0299 (turbo underboost code) I have cleaned the map, maf, checked the vane position sensor and checked all the boost tubes and boots...
Exhaust that is.......i have a 07 lbz with a edge cts, all stock otherwise. should I order 4 inch or 5 inch turbo back kit?? Wanting options and any advise
