Just come back from another dyno session today, seeing 133-135 rwhp on a 1999 996 SPS:D:D:D

I think Heners got 130+ at the rear wheel of his FE last year, that was with pipes and a new ECU. It would be interesting to see how this could be improves with a power commander as well as a set of the new style under tank filters from JHP.......................any comments!

but henners has 130 grunty, easy to use v twin horsepower:)

and a clear conscience!
