Pettit racings anp tune
 

I have a 2009 r3.Has anyone bought the anp package from pettit racing?Includes racing beat exhaust,K&N filter for stock airbox and dude logger device.If so what results did you notice?

I think it is better to put turbo Greddy 0,7 bar

The results come from the use of a sports catalyzer or a straight pipe.. changing the cat back does close to nothing power wise :)
@Bob: fitting a turbo to an s2 rx8 is still unpractical tuning wise and the small mechanical differences make it a hard task to fit a greddy turbo without other modifications.
