A simple question that i seem to be getting varied results from looking. Are SP camshafts different to SPS cams?
Yep. The SPS (916/996) used the T1 cams. SP used a pretty stock exhaust by the looks of things with a bespoke inlet (a bit longer duration)
Cheers Nelly, that explains why it's not fuelling right on the SPS i am working on. Opened ecu to find a standard 916sp eprom inside. The joy of building from boxes of bits.
