My 1st engine Ahmed chip with 16psi(the 1 that was in car when bought) came with 179bhp (PTS figs)

I had a Piper T2 added and a GRS EVO3 inter fitted & set up and power was 155@wheels(AVA). It was driven hard & it eventualy let go.

To answer your question I'd say 155@wheels........175bhp (ish, fly) would be the figure id put on it!
