I have had the ECU in my SL55 reflashed (Renntech. In addition I installed the larger pulley and carbon fiber air box. The performance change was phenomonal. It made the stock 55 feel sluggish in comparison. Renntech claims an increase of 30 hp for the ECU, 20 for the pulley and 15 for the airbox or 450 hp. The big change is in the torque. 30 ft. lbs for the ECU, 30 for the pulley and 20 for the airbox.

It is well worth the change about $9500.
