Engine and accessories run and operate exactly like stock with the UDP. I can't say that I notice any increase in engine power but the car IS faster on the track. I picked up about half of the difference in acceleration between my BSX and the 500 lb lighter BSR Spec Boxster race cars. If I could find one more equivalent upgrade, I could give the BSR guys a run for the money. Overall, a great upgrade for the price.

That upgrade is headers, on my 986 they provided at least as much change as the UDP, and maybe more.

hi ghost.
was wondering which headers you use on your 986, and do you experiences any loss in gain at low mid RPM?

thanks.
