Just took the Boxster down to Protomotive in Arkansas this week. They were able to tune my 3.4 for 50 more HP over the stock 996 program that was in the car. It seems that I am much more likely to get in trouble now
Seriously, Todd at Protomotive really knows his stuff, and, apart from being the least accessible Porsche shop in the country, it was a great experience. He was able to tune the car for all of the different components (Cayman airbox, Fabspeed exhaust, etc.), and it runs beautifully. Interestingly, on the drive back, the extra HP didn't really affect the mileage at all.
This is now that car that I've always wanted - mid-engine, light, tons of power.
If you're in the middle of the country and want to get the most out of your car, I recommend contacting
Protomotive.
