Wow... Interesting. Your vehicle could of had underlining issues though and the extra power + heat didn't help. You stated your transmission had been leaking/seeping from the transmission pan. Less fluid = more heat = transmission failure. I have been on the fence of getting a 65mm steel pulley from that guy from Poland and a EuroCharged tune.

You would think you would want to have a wideband if any sort of tune with added boost was added to your car also.

Did you get the TCU tune also or just the ECU and pulley tune?
