Like you I wanted a dyno tune, which as we both know can be done with the sepst. Unfortunately, no dealer within 250 miles wanted to attempt to tune with the street tuner. One certified HD tech even said there's no point since he cant make any adjustments, and went on to say the stage 2 download work great and nothing more needs to be done. Figured there's no point trying to convince him, so I moved on.
One thing to note is the stage 2 file is for a stock headpipe and streat cannons. There is no seperate tune file for the high flow exhaust even though its in the options menu. After the stage 2, it took several 'smart tunes' to get it to run decent. The ATM made it run way way better; it was immediately noticeable. Plus, due to a points system at my dealer, I was able to purchase the ATM really cheap.
good to know about the calibration discrepancy for S2...and that you got things worked out with auto tunes and atm and are pleased now with the results...there's no question I'd rather have your exhaust over the OEM, just all came down to $$$/value which means different things to different folks..ride on man!
