If you do this upgrade don't forget to upgrade the brakes too. If you've got extra "go" you need extra "stop". If you change the rev limiter in the a 3.2 then you should change the rod bolts and the valve springs/retainers. 3.2L cars are limited by valve float above the stock rev limit which is why the 3.2L Club sport used different (lighter) intake valves for a rev limit increase of only about 300rpm. Also the rod bolts on the 3.2L cars are a mm smaller than on the 3.0 and are a known weak spot. Other than that all I've heard is good things about the knowledge and quality of the protomotive group, but I have no first hand experience.
