Are we the only two guys that have done this kit upgrade? How do you guys fault the SERT?

[1Trickydick]

I don't think they are blaming the SERT.  By tuner they mean the technician that does the dyno tune.  As was said in one of the above posts, few of the very best Tuners (technicians) work for a Harley dealership.

Well I have my bike scheduled to get re-tuned this Thursday. I changed the exhaust from the rinehart true duals to the Vance and hines power duals and 4" rinehart slip ons and I definitely noticed a difference in the seat of pants feel but we will see what the dyno says. Btw this setup sounds awesome

Others know more but i have been told by many different sources that high temp. and low humidity will take the numbers down. You want cool dense air to make power and you had neither on that day.80 degrees and 5% humidity is about as bad as it can get, my .02 worth.

[Dr.D]

Yes if you want to post big numbers tune in the winter. Keep in mind come summer you will not be producing all that power. Nobody's bike does, so it's a level field.

I do understand the point about the SERT and the technician variability.

80 deg and 5% is about as good as it gets during the summer!  Try 80 deg and 95% now that will make the #s really look  like s**t

I just picked up my bike after having the Pro performance upgrade kit installed.  On my dyno below is my bike last year when I had the following done to it, install Andrews 54 cams, adjustable pushrods, .030 head gasket, Ventilator air cleaner, D&D fat cat.  Bike had OK numbers but stumbled on the lower end. Tuners in my area could not resolve it.  Decided to change and install the Performance upgrade kit from HD. So far the little bit I ran it, it runs good.

Had the local HD Dealership tune mine and it was not good.  Ran it up to Jason at Fairbault HD and picked up 10 HP & 12 TQ as well as better throttle response, less heat and improved gas mileage.  The person doing the tune is the key!!

Crunch29 those numbers look real close to mine but I have less of a dip at the the low end.

How many tunes does a man have to get to know when he has found the best. It may even be possible to find a good one at the DH.?

I work with the guys at Smokey Mountain HD what is their reputation?

[crunch29]

My dip I believe is associated to my pipe. I have the performance baffle and have been told I could use a little more back pressure. I really didn't expect my numbers to improve. I was just looking to get it running better.
I had contacted Steve at Fullsac and was going to trailer my bike down to him and have a TTS tuner installed and have him tune it. I'm sure he would have corrected my issue.  That trip would have cost 3000.00 or better.Plus a week of vacation.
 I had this work done for half that cost? So I figured what the heck.

About tuners, I wish I new what tuners were good at the dealerships.  In my area we don't have a lot of shops to choose from.

I know nothing about the guys from Smokey Mountain HD. So can't comment on that.

My next change is the 30t gear.

Not sure how far you want to go, but Dusty Warner at Alefs HD in Witchata KS is one of the best.  My final tune was 052.drf, so he spent some time on it.  He also did all of the head work himself.  You can check out here dyno numbers on their website under their 100hp club.  I'm #3 with the strongest 110.

Crunch I'd bet you are correct about the back pressure. I had the wife's Softail upgraded and with 2" baffles in the Rush pipes and got the same tq curve. We went back to the 1"3/4 baffle and it magically disappeared.


Protor, what kind of modifications did you have to do to get those numbers? They are good.

[Proctor]

Ported 11.1 heads, 2.020 intake and 1.650 exhaust valves, Wiseco pistons with larger rods, T-mans 662-2 cams, SE 58mm T-body, SERT, V&H power duals with Hi Output, Timken bearing, welded and balanced crank and a good tune.  Dusty did all of it.  Simular to the T-Man stage 4 thumper series 110 kit.

That does sound a bit more work than I did no wonder you got the HP, fine job.
