i went with the Master Tune and it was worth the money .. maybe not all the money

but i definitely got a major increase in power & torque

 

So you are going to what spend like $400-$500 for a decent dyno tune.. and beat the crap out of your motor and you think you got a good deal... OK.

I would suggest you spend the $100 to upgrade to TTS and save your machine the stress... but regardless thats cool.

 

I agree, I found myself next to a Dyna one day at a show and a customers bike was getting looked at, I had to walk away, the amount of times the techie cranked the bike to full throttle and held it there made me wonder if the valves were going to blast through the engine, I went for a Thundermax with auto-tune and it works fantastically, and according to my logs I have only reached max revs for a few seconds so far in 1500 miles. No stress going on there.

Horses are up and torque as well don't know by how much but I know they are up jsut from the feel of the bike, after all they are only figures if it feels great then thats half if not all the reasons there.

 

I have a 2003 EFI FatBoy that has the Screamin' Eagle Hi-Flow intake, original Screamin' Eagle 2 mufflers, and a SERT. When the Race Tuner was installed the correct "download" was also done on the bike.

The bike ran great with this setup, but I decided to take the bike to a tuner that knew what he was doing and had a complete Dyno Tune performed.

Bottom line, picked up an additional 8 horsepower at the rear wheel.

The 'stock factory downloads' might get you in the ballpark, but they will never take the place of having a good Dyno Tune performed.
