Talk to Jo Borras at Renntech. I am positive it makes much more than that. I think the tune also creates better gas mileage. I was planning on doing the same for my 2003 SL55, as the IC pump is bad and sending off all sorts of messages to the computer and temperature gauge. Jo, Bob and Hartmutt are great guys.
