Tuning The 120R
If my 120R bike was my everyday rider I probably would have chosen a different pipe, but I was looking to build a tire shredder and the Dragula seems to be the 1 of the best pipes out there for my Pro-charged 120R build. I have a 2010 SG with True Duals that I use for my long rides.

The drizzle stopped and the sun popped out briefly so I wanted to try the program I worked on last night. It was mid 40's temps so that made for a good trial on my start up changes as well.
The bike idled all the way through the warm up steps perfectly vs. the base map had the bike surging and even stalling once due to the lean programing.
Took it for a 20+ mile ride through the local back roads which consist of several elevation changes and plenty of twisties. I could not make the engine hiccup, flat spot or perform any kind of anomaly that makes me feel I need to retune it.
I know the exhaust I have on it is restrictive for a 120" engine or I would leave it be since it runs so well.
If anyone that tunes their own bikes with a 120 would like to try my map, I would like to hear the feedback.

Yes but not until after I get the Fullsac pipe, 2.25 baffles and a clutch kit.
Problem around here is the lack of a good tuner with a dyno. The Harley shop has a dyno but I don't know of anyone that has ever tuned their bike there.
He'll do a couple of runs for max power and O2 readings for a reasonable price so I may start there.

Can you post your VE tables? I have 2008 RKC and Supertrapp 2-1 and everything else is great but idle and light load is anything but smooth, I'd like to compare the top left

They can set you up with a break in map and then do the final tune.

My 120 runs perfectly fine with my tuning in it and I'll bet there is not an additional 3% to be gained if I were to trust someone to tune it.
My goal is to buy my own dyno in the near future so I can spend the time necessary to produce maximum results.
Unfortunately most tuners are worrying about the boss looking over their shoulder bitch'n about how much time they're wasting which is the case at the one shop where the guy actually can hear and feel what's going on plus understand what the graph is showing him.

I thought I saw a portable DJ dyno for sale in the clasified, like $8500.
Ever try DTT Twin Scan and the WEGO? I've never tried it, just asking.
