The auto tune doesn't do timing just AFR.

It was a tough decision between the Thunderheader and Vance & Hines Pro, but I went with performance over quality. My pipes are already golden after the dyno, but who really gives a **** when your bike now feels like a f*ckin missile! These pipes are loud as hell too! My engine is stock, so the dyno #'s may not be that impressive, (75 max hp/91 max tq), but I can definitely tell the difference over my previous exhaust set-up. I shot my savings wad with this upgrade and couldn't be happier! Cams, heads, etc. next. I've attached the before and after pictures. Yeah baby!
How did you confirm the stage 1 download? Do you have a tach and seen it go to 6200 RPM? Did you have the dealer download it? Many people added slip ons and intakes without the proper download if you bought it used. I ask because I remember in one of your threads you stated your bike came that way with the stage 1 already. The download made a big improvement on mine but I have the heavy breather which according to the supplier (K&N) and Harley makes 4 more hp than the regular stage 1 intake with the open back.

You gotta love the haters out there bringing completely content people down on how they WASTED their money. Easy f*#kin come, easy f*#kin go dude. As far as confirming the Stage 1, I took the dealer's word when I bought it used. Who knows if it was legit or not. All I know for sure is when I took the bike out again this morning for an extended ride and hit 100 mph on a back road, there was still something left before I slowed her down. My previous set-up would hit a wall around there. It's also running 20 degrees cooler. I'm a happy dude!

I am not trying to bring down your high, just curious as you stated you can tell a difference. If you are happy that is what counts. Stock 2010 bike with cats hit 116 mph top end according to the magazine roadtest comparison against the Triumph Thunderbird last month.

Harley-Davidson Dyna Wide Glide Triumph Thunderbird
•Price $14,499 ($14,718 as tested) $12,499 ($12,799 as tested) Dry weight 643 lb. 710 lb. Wheelbase 68.2 in. 64.5 in. Seat height 26.6 in. 27.5 in. Fuel mileage 36 mpg 32 mpg 0–60 mph 4.8 sec. 4.7 sec. 1/4-mile 13.31 sec. @ 97.96 mph 13.24 sec. @ 97.31 mph Horsepower 63.3 hp @ 4730 rpm 72.6 hp @ 4600 rpm Torque 81.1 ft.-lb. @ 3410 rpm 95.1 ft.-lb. @ 2630 rpm Top speed 116 mph 118 mph.

Their HP and Tq figures were each 3 low compared to a non catted bike and the stage 1 adds 8 hp and 3 tq according to HD SE catalog. My bike is still pulling hard at 95 mph and I comfirmed the download with the tach as it is willing to pull to ~6200 now up from 5500. Can the superfat FB front tire cause such a difference because of drag?

Anyone care to share their TTS tune? I'd love to look it over and compare to some stuff I have been messing around with.
