125 rwhp, 77 rwtq...thanks Devious

Before I get started I have to thank the nicest guy I've never met...Devious. His posts on this site as well as on Triumphrat.net have proven to be invaluable. His knowledge of engines makes him a tuning guru and he unselfishly shares his latest findings, usually with photos. The removal of the exhaust precat, the removal of the SAI, the DIY advice for ceramic coating, his posting of tuning maps, his review of his Trident half system, the suggestion that HD dealerships probably have a dyno and more tuning experience than Japenese shops, ...the list goes on. He has patiently answered all my emails/pm's, walked me through some routine (for him) stuff, and encouraged me to do some of the work myself. His substance over BS posts keep me coming back although Cheapbastards sense of humor does keep me laughing.

I have a 2006 S3 with 2200 miles on it. I ordered the Trident CF half system and when it arrived I took the "Y" pipe and my header to HD of Frederick. They have a kick a$$ machine shop and the machinists/fabricators to go with it. I talked to Mike Shultz, a top shelf guy, and told him what I wanted. He removed the precat and ported the headers and sent everything off to be ceramic coated. When it returned I installed everything along with a BMC air filter. I then went to Fredericktown Triumph and talked to Jerry Gentry the Service Manager, another top shelf guy. He removed the SAI and installed Kuhlka's block-off plates and installed the Triumph precat removed-SAI removed-high pipe tune.

Today I rode the 35 miles to HD of Frederick at 8am in 22 degree weather. My hands were frozen after 20 miles and when I arrived my johnson looked like a swizzel stick and my boys looked like raisenettes. Anywho...Mike Shultz put the S3 on the dyno and it made 125.13 max rwhp at 9000 rpm and 77.65 max rwtq at 7500 rpm. The air/fuel is lean at full throttle and I'll probably clean that up and squeeze another few hp and tq with a Tuneboy. For now though I'm pretty happy with the results. Thanks again Devi!

As I stated on Trat, Devi is da man! I personally can't thank him enough fer all of his help. And as Tight said, I've never even met the guy! :afro:

You boys are gonna make me blush!

TightTL - It's GREAT to here all is working out. My bet is that if you are running the 20088 tune that you are leaner than you think from peak torque through 9200. Add 2% more fuel up top and I bet you get even better numbers.

Other than the cold, how is it running these days?
Devious,
Is the 20088 tune that you mention from a tuneboy? I am currently running the Triumph tune, whatever that is. The dyno guy did mention that the lean condition, while not eyepopping, did need to be corrected before I did any other mods.

I just got back from a ride. In this weather I just ride from bike shop/Starbucks to bike shop/Starbucks to try to stay warm. The S3 is running great although I think I notice a slight surging from time to time at steady/trailing throttle at certain rpms, but it could be in my head. The acceleration is staggering...makes me want to get slightly lower handlebars to be a little less upright and a little more bend over.

You are getting 125 hp on a stock tune? WOW.

Then you are definately lean in the midrange and top end. A good bit more power is available with tuning.
I may have confused you...I am currently running the Triumph TORS tune for SAI removed, precat removed, aftermarket high pipe installed set up. It is not the stock tune that the S3 came with from the factory.

Ah HA!

Yep, not hard to confuse me. As easy as shooting fish in a row, or ducks in a barrel, ...or something like that.
??? Tight TL or anyone else, when he states he had the Triumph pre-cat removed, sai removed, high pipe tune installed, is he refering to the dealer Arrow high pipe slipons tune??? Also I did not realize that the dealers had a tune for sai-removed and pre-cat removed along with highpipe slip-on tune-is this true??? If so I should be able to remove sai, precat, install block off plates and arrow half system and get my dealer to load this tune and hope for similar results!
Also I did not realize that the dealers had a tune for sai-removed and pre-cat removed along with highpipe slip-on tune-is this true???
Yes, you're dealer has several tunes for different set ups:

stock / low mount / high mount aftermarket mufflers
SAI, Non SAI
Precat / Precat removed
for older and newer ECU's
I would definitely NOT do this.

In TightTL's graph below, notice the red lines - especially the air/fuel ratio. From 5000-7000 this is not just lean, it is scary lean. Bad thing happen when bikes are run this way.

Notice the difference with the blue lines - after tuning.

:wtf:
I assumed that the "dealer tune closest to a given setup" would give a pretty close to perfect result.. never realised that it could be so far off
THANKS, Devious/Buster this is good to know. TL's mods are inline with what I was planning to do, pre-cat and sai removal/block off plates with Arrow half system. :wrench: (Devious)? Do you think the dealer tune would be a bad idea as a starting point if I were planning on getting a tuneboy fairly soon or should I just wait to get it?? Also is there a pre-set tuneboy tune that will work well with these mods without dyno time and tuning ??? :drink:
The dealer off road exhaust tunes will have the results shown in the graph above - red line. WAY too lean. Do not use the Arrow tunes on a high mount exhaust.

What year is your bike?

There are about to be several good tunes available in the DOWNLOAD section of this site for high mount exhausts.

I forget exactly where the bikes are sold, but it's 6:30 in the morning, and I haven't had coffee yet. I believe the S3's sold in Australia and possibly S. Africa ship from the factory without SAI or a pre-cat in the header (2005-early 2007)

Naturally thy require a different tune, thus Triumph has one.

This is the normal TORS tunes without SAI - 20103, 20112, and 20170
20103 was used in the graph above - red traces.
(Devious) :wrench: ??? My bike is a 2008 model. I was hopeing to get a tune that would work with these mods without dyno time and tuning, since its just a exhaust mod and sai removal I thought a simple tune would be all thats needed but I quess this is more complicated than I expected Will I need tune boy to get the downloads from here you mentioned or will this be a download the dealer can get to his handheld programmer??? MY mods will include Arrow Half system, pre-cat removal and sai removal with block off plates with bmc filter. Thanks.
You'll need tunedit (tuneboy) to load files from this site onto your bike. Your dealer could do the stock Triumph tunes.
Just came from dyno,

Speedy kicked 117,88hp @ 9328rpm and 96,48Nm @ 7597rpm

Airtemp=9 AirPress=1016 AirHum=63

Zard full exhaust, K&N filter, SAI removed, Harris tune.

Man said that the dyno is quite critical...

Got a 5Nm notch @ 5000rpm what has to be fixed...

VERY true words.

The numbers are about what I would expect from most low mounts. :drink:

Try retarding 3 degrees around 5000 and adding 1.5-2% more fuel.
