Thundermax auto tune. I just need reliable. Complete replace of the stock ecm. Did stage one with S&S Stealth Bobber air cleaner, Python Staggered Duals and the Thundermax Auto Tuner. Have an '05 Deluxe with the 88 Twin Cam. I'd had an '09 Dyna with the 96 previously. Wanted something to put some pep into the '88. This is what I went with.

"SERT" because Back in 07 when I did the Stg1, I had it installed and Dynoed, it was about as good as one could ask for at that time.

Only time I've touched it in 8yrs is when I added the cams in 09 and they Tweaked the tune for the cams,, since then, the SERT had been totally trouble-free. I haven't had to touch it at all.. Its now called the SEpST

Now there are several more/other Auto-adjustable systems out there,, If I was to get another new bike, I'd still probably go with the the SEpST.. I just don't like to mess with the tuning .
