I finally had enough! After all the crap I have had with this tuner Im sick of it. I really think my autotune was defective. First issue was dead batteries (bought a battery tender) then after hours of calls I sent the unit back to Nick who sent it to zippers, who sent it back to Nick who sent it back to me....said they found and issue ...it was missing a driver.....same issues, idle sucked, sounded like I had the cam from hell, battery still went dead, sluggish performance. I started calling zippers.... after talking to james, turns out I had "Beta" software! Now why the hell they didnt see that when I sent it in is beyond me! I talked to James some time back and sent him my map, but never heard back from him, nor did I get the revised map back. I know he is busy dealing with all of us with issues, but damn! For as much as this unit cost it should work right. The theory behind this unit (autotune) really appealed to me and I tried...man I tried....but now im back to the race tuner and pissed I wasted so much time and money for nothing! Thanks Guys and Gals for letting me vent!
