ESS Direct Flash tuner

Eloy at RPI just set me up with an ESS tune. He had tuned my M6 with an ESS tune already, however, it has always been a hassle to get to his shop for an update. So when he installed his exhaust on our X5 M, I asked him about a tune for it. He told me the ESS tune was going to be available with a handheld tuner. I had used a Diablo tuner on another car so I thought this would be a convenient way to flash the car and give me the option to restore the factory tune if it had to go to the dealer. When I got the tuner, I downloaded the factory tune to the Direct Flash tuner (it took about an hour) then emailed it to Eloy. The next day he sent me the ESS tune. I flashed the car the next day (that took about 10 minutes). The difference is significant.The increase in power throughout the powerband is impressive. ESS estimates the power increase at 60 hp. I believe it. If you're considering a tune, you may appreciate the versatility of the hand held unit. Eloy has always treated me well.
