987 Cayman and Boxster Modifications
I got a low mile 987S 3.2 Boxster, 280 HP stock. My car has a Softronic remap, IPD plenum, 74mm throttle body, Evomsit V-Flow system and a cat-back DesignTek Valvetronic exhaust... So it should be at least 300hp or more, but it has only 271 on crank.
Any suggestions where are...
