Hello all,

I got my Hypertech tuner today and it didn't work. Start up was fine,it read my VIN which tells me it wasn't Vin Locked, then it read my PCM, it got to 100% and then gave me an error Code 6D: CAL NOT FOUND, which translates to Calibrations Not Found. Has anyone experienced this problem with the hypertech? if so how did you fix it?

 

where did you get it from??? I have an 05 lt too and had a hypertech on it for awhile and it worked fine
