That all said, I did look over my install pictures and the car itself and sadly I can't find any other major upgrades that I should be aware. I was really hoping to find the crank pulley and cooling upgraded, but it wasn't. The real question is what tune was on this car before? I've emailed all the major tuner and gave them my VIN to see I can find who it was. Kind of a shot in the dark if any of them reply.
As for the EPL Stage 2 single pulley tune, it certainly has a lot more low in torque and generally more power along the full range. It is simply stupid easy to break loose my all season tires on a slightly wet road with traction control set to off. I'm ditching these tires went spring comes as I'm getting winter tires install this weekend and hope to run summer tires next post winter. As for the tune I'm happy with it. I've very interested to see if my MPG improve now that everything is back in sync. Only time will tell...
