I swapped my S4 upper and lower intake for the S5 setup, used the S4 TB, got everything in and fired up, the car starts and idles, but if press hard on the gas pedal it bogs down then revs high, if I let off the pedal sharply it will stall. It feels like a fuel pressure problem, does anyone know what the stock pressure should be, and any other ideas on what the problem might be? Any help would be great.

 

About 33-38psi static - unplugged at idle



Sounds like a TPS problem.
