Great services externally fast turn around time. The only thing would be the need to up their packaging. I know it's the mail carriers fault but 1 bubble wrap envelope would protect my ECU from damage. It still works but it's damaged now.

This 2nd tune with the new injectors feels much better. Gas millage went up to where I thought it should be. Idle still has a bit of lope/mis (cam?) and "dropped" once to 200 rpm that I feel is probably a throttle body issue. I might be changing that next but will wait to see if there continues to be an issue. Thank you for all your help!

I have a 2011 grand sport corvette ls3 with auto.I needed it tuned for the new cam and to delete rear o2 sensors. Also car had a low idle. Can't believe how quickly I got it back definitely 5 star on shipping. But I still have a code for one of my rear o2 sensors and car idles to high I can barely hold it at a stop sign,and can not hold the car at all on dirt. I have to put it in neutral on dirt. They didn't advance the timing enough for my cam ,I am willing to bet it was advance half of what it...
