I have an issue were the car with drive and boost fine if i slowly press the throttle down until WOT but if i just got full WOT it will immediately bog and hesitate throughout the rpm and the boost jumps around sometimes spiking higher than set (Tru boost set the 13psi). The strangest part though is that it does do it all the time, i recently recirculated the BOV and got a new intake setup and that seemed to help but it still does it. It feels like the engine is dumping to much fuel in, no wideband yet so not sure. I just want some tips of what to check Thanks. (new cts, plugs gapped .28 1 stage colder, did blt)

OK, did some test and it seems like fuel is building up in the cylinders and causing it to bog/stutter under WOT. Did a WOT pull tonight and it stumbled backfired then pulled like a champ also it seems if i run the tru boost in "OFF" mode the issue doesn't happen at all so maybe the solenoid is faulty. Still open to opinions/help.
Thanks

More then likely wires or coils, and get rid of the tru boost and go with turbosmart I have a manual in cabin and its the best controler I have ever used. BY FAR locks at 15 no spiking or anything and I have a stock s14 turbo and wga for now
