performance enhancement
I want to give my 201 hp 2.5L 1999 Boxster a power boost. I know I have various options > air intake, exhaust headers, chip reprograming, bolt-on supercharger, etc. My question (first of many no doubt) is what other changes, if any, would have to be made to accomodate these power enhancements? Are all of the changes mentioned within the tolerances of the stock engine? Also, any recommendations on aftermarket companies?
