"have a Boxster-S and upgraded the intake with EVO, by-pass cats, and sport muffler from Dansk along with GIAC ECU remapping. I have noticed a real difference in power from the start all the way through the RPM. In fact I just came across another post on Pete's Boxster page from Andy in Oregon that done the EVO and ECU but with headers and sports cats and dyno the car before and after and he is getting 35+ HP at the rear wheels.

The GIAC engineers feel that the ECU re-mapping gives more gain on the 2.5 and 2.7 than the 3.2 (they feel Porsche tuned the S more from factory than non S).

I know there are lots of postings that say no gain, but you have to do combination of things together. Just putting EVO without re-mapping will not give you that, or installing the header without the more air-flow and ECU.
