Mefi 3 tuning help
 

Hey guys im new here and never really used a forum before but bob at mefi burn hasnt been much help. I need an ADX file to scan a mefi 3 controller part #16237009, as i only have the XDF file used for the tunerpro. The controller is also locked, yet he claims its unlocked and offered no help when my dad paid $500 for a base tune file in addition to all this software. Pretty frustrating. I have experience using hp tuners but im trying to tune my dads 98 cobalt 253 with a procharged 502 that has a cam, fully forged block and aluminum heads. Any help is appreciated. Thanks gents.
