26hp from ECU and Pullys? ESS is claiming a 30-40 HP gain just on the ECU, I guess we will have to see the dynos. ESS is saying that there is alot of power left on the table from BMW, so thats why they are claiming these numbers I guess. I personally dont think that just by ECU 30-40 HP can be gained but I may be wrong.
