It actually effects it more that what you would think. When the butterfly's open all the way instantly, it makes more power in the lower RPM's and it carries some of it up to peak RPM's. Not to mention, when you are tuning a TBW bike that doesn't have it turned up, for a wide open pass you have to tune the 60%, 80%, and 100% throttle position at certain RPM's to get your air fuel set right. For instance, a TBW bike twisted wide open at 2000 RPM's might go to around 60% TP from 2000 to say 3200 RPM's, then get near 80% TP untill, say, 4200 RPM's then finally go wide open at 100% to the rev limiter. A proper tune means that you would ajust the 60, 80n and 100% VE colums from 2000 tp 3000 RPM's, the 80 and 100% VE from 3000 to 4000 and the 100% from 4000 on up

I know Latus has a good reputation, but I'm wondering if that rep was established when Mike Stegman was doing the tuning. He's the shop foreman now and rarely gets in the dyno room.
Have you thought about taking it north to Jarz performance? I've heard very good things about them. Don Dorfman (Deweys Heads) recommends them.

I had considered Jarz, but the hassle of crossing the border back and forth kind of makes that less appealing, but still worth thinking about. Distance-wise, it's pretty much a wash, I'm about half-way between the two shops. I wish they were as close as Don's shop, which is about a 20 minute ride from my house.
I'm going to be pushing my compression a bit, and don't want to be fighting the ping monster.

I've heard similar things about the tunes coming out of Latus in the last couple of years, but they're still head and shoulders above the dealer tunes here in the Sea/Tac area. If you're building with mostly SE parts, they still seem to do a pretty good job, for the most part.

Yeah, that's what I was thinking, too. It would probably be a much nicer ride than the run down the 5 to Portland.

Wow, 99 Hp is INCREDIBLE for the 551 S&S cams. Who did your Dyno tune,
amd could I possibly see your printout? Good torque numbers too. I AM running a trike (my tuner says to figure in about an 11% loss because of the drive-train, plus I addded many heavy duty options, so more drag exists). I have 75 HP and 93.5 Ft. Lbs at my posi-traction rear wheels.
Very happy with the results, but could use more torque puling my laarge camper.
Thanks, Stoood

The 392s are definitely cool and improved. But now commuting so much I can't wrap my head around bad mileage, premium gas and 70 miles per day. I got a little tired of driving a 200" long car after a while too.
Btw, I'm trying to figure out actual drag race times for Harleys, from stock 88s to built 103s and 110s. If you have some general times, can you PM me?
New Build
2008 Ultra Classic - Upgraded to 103" Motor with 10.5:1 HI Compression pistons, SE 255 Cams, Evolution Industries front sprocket, SE Super Tuner, SE Air Cleaner kit, Bassani Road Rage 2 into 1 Exhaust.
110FT Lbs. TQ 93.5 HP I love the feeling of the front wheel coming off the ground on an Ultra Classic.
