Sounds liek a fueling issue possibly then. Get Doug to check it out.

[QUOTE=Rossco;570917]Is the factory MAP sensor still plumbed in properly? (along with the pressure exchange solenoid)
Is the stock boost solenoid still plugged in electricly?

It sound like the typical Rs Lib limp mode.[/QUOTE]

hey yes all plugged in and yes the stock boost soleniod is stil electricly plugged in but nothing else connected on it.

im thinking of putting my power fc i just bought in and wiping the tune to stock pfc tune is it okay to do this ??

and will it be better for the engine ??

Try to read the ecu's error codes first. There's a write up on here that I did ages ago. Search for "ecu reset" or "ecu code read" or similar.

Find out if it's going into limp mode.

i have already done the ecu reset and tried checking for codes i will go and try again but if i get no codes im going to try install the pfc on the base tune and see how it goes, next ill probly look at coils and fuel setup.

My old RS did drive. Drove ok, got hot, would run like utter shit. '

Ended up being fuel pump

well i just did the a code check and im getting 23 just kept repeating 23 so thats the afm i will change it and see how it goes.

and i just put a new fuel pump in but im thinking it mite be the filter or injectors.

swapped afm, reset ecu but still getting code 23 ??

Code 23 on obd1 is pressure sensor (map) is it not.... I'm on iPhone & can't check.
