My plus 4 Duratec has a Williams manifold, exhaust and remap. I had occasion to put it on a rolling road (emissions issue) and power had increased to 155 at flywheel and torque to 148@4800rpm.

You certainly won't get the results with a Duratec that you will with the GDI.

I had emissions issues with the Aero Racing manifold and cat (same manifold and cat as the Plus 4 SS) fitted to my car at the factory. I resolved the problem by fitting individual throttle bodies and a Omex ECU so that I could do my own tuning. How's that for logic laugh
