I'll tell you next week. I have an 02 EGC with 95" engine, 203 cams, PCIII, Reinhart true duals & SE mufflers. The stock mufflers were 'way too restrictive, & I went with a set of barely legal SE slip ons. Then, over time, they just got too loud. I then installed a set of 2007 SE slip-ons. The tuner 'ran into a wall' with those mufflers as the "sniffer" has to fit past the mufflers & into the tail pipe. The late-model SEs have a baffle about 1/2 way up so the tuner didn't want to waste my $$ by doing an inaccurate tune.
That caused me to go to Fuelmoto & get the ThunderMax with Autotune. It's being installed even as I write this, but the weather is so bad I'm not going riding until the rains clear up.
So, I'll let you know next week. I'm hoping to get better gas mileage as I'm not a hot-rodder, but still only get 34-36 MPG.
After I installed my oil temperature gauge, I had a sneaking suspicion that maybe my engine wasn't warming up enough in the winter weather to get the Delphi off whatever the EFI equivalent of the "choke" is.
I found Jamie & FuelMoto to be excellent to deal with.

I noticed that on your sig, your sold '02 had the PCV with auto tune... Did you change to it with TMax problems? Thanks

I am new to Harley's, and my experience is only with the Tmax. The reason I used it is I started with a wrecked '09 bike that didn't have an ecm when I got it. I would've had to buy, and pay a dealer to tune a factory ecm before I could even run the bike at all, and then re-tune for any changes made after that. The tmax is kind of expensive to begin with, but it wouldn't take very many trips to the shop for a re-tune to be even more expensive. It is very easy to adjust for upgrades and my bike has run like a champ with it so far.

the limiting factor with the Thundermax is in the base maps. If you go PC5 from FuelMoto, nobody has more maps to support it than Jamie, hands down.
With my 03, I had PCIII's and after the second one peed the bed, it was time for an upgrade, and since I had newer headpipes with the O2 bungs, I went with the Thundermax on the recommendation of the shop that does a lot of the bigger jobs on my bike, they did the cam and cam plate conversion on this particular bike.
I spent some time looking for a comparable cam ( lift/duration) to my 509 cams that was in the Thundermax map database.
I found one that was close, plugged in a few values and so far so good. If I am going to get the full monty from it I need to get it on a dyno and play with the timing side of the maps, and that has not been a priority for me..... maybe this winter...
The Thundermax autotunes to the A/F ratios you set, I am almost sure it does not auto tune for timing.
I have the shop manual for it here, it is as thick as a NYC phone book. At some point I need to thumb thru it, but for now I am thrashing the 13 Stage 4 for my performance fix.... the 03 will never come close to that 110/110 feeling no matter how much I play with the timing

You are right about the Tmax not auto tuning the timing. It is pretty easy to adjust timing yourself using a laptop. You can also make changes to the fuel settings and turn off the auto tune if you want to.

I'm also in the market for an autotune and was strongly going for the thundermax but if it does not do timing which tuner does?
I'm going to be installing 2p4 cams in my 08 sg it already has true duels with Reinhardts and high flow
