I recently bought an Auto-Cal from a reseller for the purpose of getting emailed tunes to match bolt on performance items for my 97 Vette. I had some initial problems with the unit that the person I bought it from did not help me with but someone here did. Now they are not answering my phone calls or emails to get the tunes I paid for. Went back to the credit card provider and now we are doing that dance. That being said is there a reputable dealer/tuner that can step in and sell me the tune(s) I am looking for? Any help would be appreciated.
