I'm adding some items to my '08 Sportster 1200 Custom.
V & H Straightshot slip on mufflers
Stage I EFI Kit
SE Pro Super Tuner
I got the Straighshots because I wanted to improve the sound of the exhaust. At the urging of my parts guy at the dealer I went ahead and got the high flow air cleaner and the super tuner. I've looked at the graph about improved torque and horsepower, but I'm not sure if that's propaganda or not.
The question is: What kind of changes in performance can I expect in power, torque and fuel consumption?
I have the straight shot slip-ons as well, you'll like them. They sound really good. You will notice a big difference once you complete those mods, i'm not sure of the exact numbers but it will be noticeable even just using a "seat of the pants" dyno.
