[Tsi]

I have a TRE spool just lyin around and I was wondering if anyone could give me some info on it. I know it's suppose to help with awd dyno's, and 50/50 to the wheels, but i've heard if your car is more of a street car u shouldn't go the spool route....is there anything else, I basically got this part so I could run on a fwd dyno safely. Also how hard is the install on this part??
