So after hearing and reading about all the great and wonderful things Doc from "http: //docsperformancetuning. Harley Davidson Dyno Tuning" Docs Performance Tuning can do to your bike I decided to give him a try. After all, I had a stage 1 upgrade, which consisted of a performance pipe, Screaming Eagle air Cleaner and a tuning device. I chose TTS Mastertune, because from the bit of research I did, TTS offers a boatload more variables to fine tune than Dynojets Power Vision, Power Commander and Harley Davidson's Screaming Eagle Tuners. Matter of fact, Ill go on the record to state The hierarchy from bottom to top would be Power Commander, HD Screaming Eagle Tuners, Power Vision and TTS tops the list. So once you change the air fuel mixture, either by changing pipes or air cleaner, you are going to need a tune. Most tuning devices allow you to download whats called a canned map, or basic set of variables that are close to your specific pipe, ac, cam configuration. These are good starting points, and some can work well or get you close, but if you want optimal performance, you need to get your ride to a reputable dyno tune shop. A dyno tune can fine tune every variable the tuning device can throw at it. So I arrived at Docs early and we chatted a while about what performance is, what I was looking to gain from dyno tune and what I would actually get from it. A very enlightening discussion to say the least. Doc then went over my bike with a fine tooth comb. Initial findings were not good. I have true dual exhaust. While they look and sound nice, the O2 sensors are not where they need to be for optimal readings. Another issue was the depth of the sensor bung. Mine were much too thick so the sensor tip did not go far enough into the pipe for an accurate reading. When exhaust is trying to exit the header pipe it travels pretty much in a straight shot through the pipe. When it hits the muffler and builds back pressure, this forces hot exhaust to walls of the pipe. Put His Hips Into It: Old Head Slaps The Sh*t Out Of A Burger King Employee! "I'm The Boss Of My House". My husband cheated on me with a 20-year-old, less than half his age, and after she sent me a poem I got revenge by sending them horse shit in the mail. Message: I called Doc a few weeks ago and after a fairly lengthy conversation, I scheduled a tune up on my 2011 HD Road Glide Ultra CVO. The bike was running great. Pajiba: Sweetened by Mock, Lightened by Droll. Here's an alphabetical listing of all our Film: 'A Little Chaos' Review: Alan Rickman And Kate Winslet Reunite For A. I couldn’t have been anymore caught-off-guard if I found a flaming bag of shit on my front porch. In preparation for the next festival, Croydonites HQ decamped to Edinburgh this summer in search of brave new performance to challenge, provoke and entertain. So if the sensor is trying to read exhaust properly, it needs to be closer to or in the exhaust stream. If that wasn't bad enough the O2 sensor on rear cylinder or left side pipe was way back near the muffler and reversion would effect the reading. Doc proved his sensor data to me by showing my sensor readings on the dyno. My sensors werent picking up any readings until about 2. So I am losing out on all that data up to 2. My true duals were considered performance true duals and the manufacturer clearly dropped the ball on this one. Besides that my baffles were 2 1/4 or 2 1. I would have been much better with 2 inch baffles. So for all of you looking to get a dual exhaust, do yourself a favor and dont get true duals. Get a crossover X pipe. This will keep both sensors by your right floorboard where they should be. With my head hung low feeling like I just took a shot to the gut Doc asked if I wanted to proceed and that we can tune the bike, it just wont be as good as with a real performance exhaust. Rush listened to tuners like Doc and made their sensor bungs short and in the right spot. They have your best interest at heart and aim to deliver looks, craftsmanship and performance with their pipes. If I had to do this all over again i would have called my tuner up first and gotten their advise on what exhaust and tuner would be optimal for my bikes performance. So, with all that said I decided to go ahead and get the most out of what I have. Doc loaded her up, strapped her down and started working his magic. At several points in the three hour process he stopped to bring me in the dyno room and point things out to me. He really took the time to share his knowledge with me and make me aware of what he was doing and why. You can tell he really cares about his work and that you fully understand what is being done to your bike. His goal is to make sure your bike runs at peak performance and as it should. Cooler running motor with less effort, better gas mileage, instant throttle response and a motor that purrs like a kitten and doesn't miss a beat. A true indicator of a finely tuned bike is to put in first gear and without giving it gas let it pull you around a parking lot with no lurching or lugging. Heck, any fool can show a dyno sheet with impressive numbers that are achieved with wide open throttle in a safe environment. But realistically speaking, how often does even the hardest rider ever run it wide open all day? A true indicator of performance is optimal response covering the range of your daily riding, not wide open throttle. We were going to take a break and run out to lunch but I had something come up at last minute that was time sensitive and I had to get going sooner than later. Otherwise it would have been great to have lunch with Doc and pick his brain from that wealth of information regarding performance tuning, Harley Davidson motorcycles and saving grace from our Lord and Savior. Maybe next time Im in the area we can do lunch and pick up where we left off. Doc wanted me to take a quick run down the road and back but I was already very late and said I would call and let him know later that day. He likes to see the cheese eating grin on his customers faces after they see the night and day difference his tune makes on their bikes. Well I can vouch for that! First thing I noticed was the throttle response. It just seemed in tune and there was no slack or hesitation anywhere. My bike responded like it was an extension of my arm, so to speak. I had an hour ride back and my glide purred along the highway with a renewed sense of purpose, like a pack of stallions running in stride and not missing a stroke. I had no decel pop or backfire anywhere in the rpm range and the engine ran considerably cooler than before the tune. I honestly couldn't be happier. Well, actually I could be. I would be a lot happier if I had stuck with my Dragula 2- 1 exhaust that could have been finely tuned better than my mgs true duals. But in the end Doc was able to still do much better with the duals than he expected. So Doc exceeded my expectations as a person and a tuner. At some point in the near future I may sell my duals, get a set of Rush or the Fullsac X/C pipe and check with Doc first on which mufflers to get then have him dyno my ride again. Hey, its a never ending process. Do we ever have enough or make enough mods to our rides? I know one thing, when it comes to tuning my search is over. I found a tuner in Mineola Florida who is considered one of THE BEST in the country hands down. So if you ever come to the sunshine state for bike week or vacation, make sure Docs Performance Tuning is on your list to stop at. Should be right up there with Disney and the Daytona 5.
