When accelerating and get to mid range rpm it acts like its running out of gas, just started doing this out of the blue.

I own a 2015 road king with all the lean and heat troubles they all have. After a lot of research I bought S&S header pipes with a cross-over port, they look like true duals, and I kept the stock mufflers. Then I downloaded Fuel PAK FP3 for touring models other systems and loaded 2 into one with cross-over or similar pipe with stock baffles. I kept the factory air cleaner.The bike is a little louder than stock, sounds more like a Harley, all the decell popping and backfire is gone, acceleration is better, roll-on is better and the motor is a lot cooler, I mean way cooler, it runs a lot better, sounds better and all the exhaust and oil temperature worries are a thing of the past.I am a little lost with all this dyno talk, air cleaner swapping and mufflers. I have run a foreign car repair center for 43 years, raced top fuel dragsters, motorcycles, and snowmobiles both 2 stroke and 4 stroke with super chargers, so you may have guessed by now that I know a little more than the average gut about tuning, and building engines. If you do not go inside the engine and you have the same cams, pistons and compression, and you have the same cam timing and the valves open and close at the stock settings how does the engine flow a lot more air with a filter and exhaust pipe, if it does it is a small amount and maybe it will be a tad leaner but nothing note worthy.Vance and Hines knows all this and they have dynoed these motors and created a software download from these stock engines and put it in their product called FUEl Pak to make it very easy for us to basically get the dyno results without killing are bikes on the dyno, ever seen a bike on the dyno, you will not like your engine run like this. In my opinion this is the very best, fastest, easiest way to make your Harley what it should have been before the EPA tied up the manufacturer with their emissions standards.I spoke with Vance and Hines and even though I was using an S&S front pipe they were very good about recommending Fuel Pak for my application, that is good business to me. Bottom line, GREAT PRODUCT, it does what they promise for a great price.

I first tried a very inexpensive tuner on my 2008 VTX1800N3. No improvement. I then put a Power Commander IIIusb on. Ran pretty good, especially in the 3rd and 4th gear power bands, but between the cost of the unit and the cost of the dyno tune, and the narrow range of improvement in performanceI didn't feel like I got my money's worth. Bought the FI2000 pro and installed it. The tuner is very inconsistent. Some days it takes over and the bike runs GREAT! other days, you would think someone put dirt in the tank. For a $450-550, frankly, I expect more. I have now installed the same unit on a 2006 VTX1800s, and am convinced it was running better before I put the FI2000 pro on it. Had it too long to return, so I guess it's mine forever. Couldn't feel good about selling it to someone else. I would not recommend it, at least not for a VTX, since that is my only experience with it.

I bought a Yamaha Roadstar 1700, got a great deal on it, it had aftermarket pipes and air cleaner but was jetted improperly causing a big lean condition. Bought the dynojet kit, the instructions were easy to follow and it came with plenty of jets for tuning. Got it all together following dynojet recommendations and it runs like a dream. Easy starts and great smooth power.

Solved my lean problem going up through gears. Smoothed everything out.

Great product. I notice a decent increase in performance at the top end that I had before. The only thing was my mechanic said that the jets that were recommended by Cobra for my bike left the bike very lean. He was able to get everything right with what was in the kit though. The bike runs better than ever and am very happy with the product.
