Midtronics PSC or Power Supply Chargers are an absolute must for “re-flashing” vehicle computers. Conventional chargers and booster packs were not designed for reflash use, and can cause problems such as program interruption (need to start over, lose time!) and, worse yet, damage to vehicle electronics (costly part replacement and even more lost time!). Do it right the first time with right equipment -the PSC Charger from Midtronics!
