I had the JCW tune installed a few months back and installed the power module yesterday. The combination of these two is amazing! I fully beleive the dyno test that has been posted before of 264 hp.

I was a little worried about fuel consumption with these mods. We went to visit my brother today who lives 150 miles away. The last time we went I had neither mod, and averaged 37 mpg. Granted this is in green mode and using cruise control. So today I did the same thing, green mode, cruise control set to between 75 and 77 mph for most of the trip. So after 300 miles, I averaged 37.3 mpg.

During normal everyday driving I expect my milage to go down just because of how much more fun the car is now!
