'09 SG Dyno Question
I recently bought an '09 SG(96"). The owner said he had it dyno'd after having the SEPST, SE A/C & slip-ons(Tailgunners) installed & gave me the printout. The numbers seem pretty weak. Also, the bike doesn't seem to have anywhere near the pep my '11 Forty-Eight had (w/similar mods). Can anyone enlighten me to the HP/TQ numbers as to whether they are decent or not? I'm selling the Taigunners & installing Jackpot 4" Dynotuned's. Will the SEPST have to be recalibrated? I had a Cobra PowrPro Autotune on my last bike and no absolutely NOTHING about how to use this SEPST. Thanks for any & all input!

Those number are spot on with those mods. A sporty with the same mods will always have more "pep" than a touring bike. Hard to tell about making adjustments after changing out the mufflers. You should not need to, but I dont know the flowing characteristics between the two

the new bike weighs alot more than the previous model- and the Sporty is ...well Sporty.
don't expect a barge to go fast, it won't-
your chart is in line with a stage 1 96".
you could pick up a little power with cams...headwork..retuning each time and giving up a little reliability and mpg at each step
it's a balancing act ( with costs) to where you have to determine what works for you.
