Cobra problem only when in boost hard

[FastNick01]

Yes I have done a search, haven't really found much info that was worth it.

Codes are

P0243 Wastegate Solenoid A Fault

P0190 Fuel Rail Pressure A Circuit Fault.

So I need a new FPRS? My tuner tuned it in with my return fuel system.

Car runs fine but check engine light is on and it feels like boost cuts out at high rpm but other than that it runs good.

I have read that a tuner can get rid of P0243 its in the tune or something? or do I need to purchase something.

Setup is in sig.

Thanks for the help.

Bump please, someone has to know something. Maybe electrical problem with the FPRS?

Are all your vac lines connected? Sounds like the frps isn't seeing the boost, but I'm not familiar with how all that plays into a return setup. Got any friends in the area that you can swap frps with? I'd try that after checking your vac lines.

Changed the FRPS. Must have been an electrical issue cause no gas saw the oil at all. Changed out and the car runs fine now.
