Anyone in the Milwuakee area willing to rent me their mercruiser scan tool for a 496 HO. I have a whipple supercharger and i am struggling with a rich idle tunning issue. Whipple offered to help me with a custom tune but I need the data from the scan tool. I would prefer not buying a scan tool. The Milwaukee area is not good for performance boat shops. I really don't want to take it into a local shop and have someone work on my boat that has never seen a supercharger. That scares me.
