The install was a bit of a challenge and took me a while, mostly because the kit was used and had exhanged hands a couple times, and things weren`t all there, but it came together and has been great, typically in warmer weather its putting out 5 lbs, and i have seen it as high as 6 in winter time temps. i dynoed it (warm summer day) at 339hp and 475ft/lbs torque at the wheels. it is ALOT of fun.
