Yes, The TTA and GNX received fuel pressure regulators with a 237 ending part number. The pressure with this regulator was about 37 psi with the vacuum line disconected. The GN's & T's had a 233 regulator which was about 34 psi. Most people run and adjustable unit set about 43 psi. I think most aftermarket chips want to see 43 psi.
thanks was just curious because i saw one forsale,and they said it was from a tta,they also said they have the tta intercooler with a larger neck inlet.
so would buying the tta regulator be worth the it,only change i have done so far,besides a complete oil change,is replace the stock exhaust with a torque tech 3inch catback
exhaust and a 2 1/2 inch hi flo cat,having my fuel pump replaced next week.
