AFAIK both the MFI and EFi made 132BHP from the factory on stock boost. Most will make the figures shown below or a few horses more (just shy of 170BHP) with a Stage 1 tune but then a -31 actuator and chip will be needed then. However, it would not surprise me if most RSTs had these mods in addition to the exhausts and intercoolers.
