I go to DynoPro. They used to be in waucanda, moved to Grayslake, & have since settled in a much nicer place in Fox River Grove. I am actually friends (outside of work) w/the guy who owns the dyno, so if you need some info...p.m. me. There is also another place in Merrillville, & the guy owns the same dyno jet dyno...I can't remember the model #,but DynoJet's latest. Jerry from SCT tuned my GT when he had a dyno day w/them, & now they used SCT software there.
