I want advice on how to bump my horsepower up to around four hundred, what is going to void my warranty? What are my installation costs roughly on different upgrades? The three hundred horsepower just isnt quite enough for me. I ve been looking at superchargers but dont know if one off the supercharged version would fit or if it would be better to get a aftermarket supercharger with more power. What about a ecu...exhaust intake ect.. what exactly will void my warranty and whats the cheapest safest solution to reaching close to four hundred horses. thx

Welcome to the forum.

Vector is right, for a 100hp more (or even less), there is just no more cost effective way then to buy a XFR, but best to ask in the right section, am sure you will get some good advices on what you could do.

 

09 XFR's are going in the high 30's. You can search inventory here:
