07 FXSTC Numbers
96 CI
Stage 1
SE air cleaner
V&H Bigshot slants
PC III
base line 73.36 HP -- 82.24 TQ
After
76.98 HP --- 86.14 TQ
Done by Horespower inc. Erie,Pa
Decell pop is gone and it pulls a lot harder in every gear.
6th gear is way better!
I had them redo the throttle body with the bore and polish.
I doubt that contributed to the numbers much since the engine is bone stock. it will be there when I need it for the stage 3 100 HP/TQ kit they offer.
these are the guys that make the throttle bodies a lot of folks use when they build. I figure since i'm only about 45 minutes away I cant go wrong.

Smoothing plays little into the numbers on the dyno graph, whether it be a Standard (STD) or Society of Automotive Engineers (SAE) readout. The difference is the correction factors used in STD and SAE.

Since engines perform differently in differn't atmospheric conditions, they developed correction factors. SAE and STD are the most common. SAE corrects your dyno run to 29.23 InHg (99 kPa) of dry air and 77 F (25 C). Si if your bike gets run and it's 86 degrees and pressure is at 32 InHg the program will adjust the numbers to 22.23" Hg and 77 F. This is for comparison. STD corrects to 29.92 InHg (103.3 kPa) of dry air and 60 F (15.5 C). STD generally produces about 4 percent higher numbers than SAE that's why alot of shops print the sheets in STD. But in reality, SAE is the more accepted (common) correction in the US. There is also an UNCORRECTED factor that shows your actual HP and TRQ numbers for the condition the bike was run in on that particular day. But it's not really good for comparison value since youd have to run bikes in identical conditions for a comparison.

Dyno Tunes in Burlington (Walkers Line and Harvester Road). Guys name is Bruce Roy. Took my 2005 Springer there on Friday; amazing work. Found 12hp in tuning, throttle and crisp, idles finally.... amazing work and worth every penny.
