Thunder Max?

Plan on a stage 1 this winter am still up in the air about what to do. Have read about these with the auto tune sounds good. Any opinions?

Autotune isn't 100% accurate. It will go in and make minor adjustments, but you still have to read the CLP's with the laptop, and then push them back into the module before they take effect. Then the process can be started again.

You'll need '09 headers, or you'll need to have bungs welded in, as the TM still uses the 18mm O2 sensors, and '10 and up uses 12mm sensors. You also lose the factory ETIMS with the TM, as the entire computer is replaced.

But, here's my story.

I installed TM with AT on my Dyna back in '08, along with pipes and a/c. Ran pretty good, but fuel mileage wasn't very good. In '09, I did a 107" with a fat cat. I could NEVER get the TM to work with that build. Even TM couldn't come up with a tune that would work. So, on the advice of a reputable mech, I installed the TTS. WOW!!! What a difference in power and fuel mileage! I never got better than 38 with the TM, the TTS is never less than 43, and on open highway, 48-50. Colorado was 58 mpg this summer! I also felt the TTS is easier to use.

I just picked up a Roadglide a couple weeks ago. It came with V&H dresser duals and cans, a/c, and the TM with AT. It seems TM may have made some improvements in the software and other things, as this one runs better than I expected. Mileage is still iffy, at about 40, and she still seems to run pretty warm on those hot days, but I think that is the nature of the bike.

When I found out the bike had the TM installed, it took me about 5 hours and a few calls with the dealership looking for the stock parts before I agreed to purchase. That's how unsure I am with the TM.

I'm very tempted to buy another set of headers and the TTS just to try. With my previous experience, the TM is better, but I still don't think it's all that and a bag of chips.

Long and the short? If I had been buying a tuner, it would have been the TTS, hands down, never even thinking twice or looking for something else. But, since the bike came with the TM, I'll give it a try again, but if it throws fits, it's gone!

Good luck in your decision!

I have the tmax in my 07 RG and I have no issues what so ever. From day one it made a huge difference in engine temps and the way the bike ran. Understanding I just need a bike that ran good and had decent power when touring 2 up. I didnt need a hot rod, it provided me with enough change in HP and torque I didn't then and still dont feel the need to spend money on cams etc.. Gas miliage varies from 42 to 50 depending on speed and if there's a passenger with me. I wouldn't change a thing if I did it again.

I agree except I do like power. And over the winter was going to take my heads off shave them and put thinner head gaskets on. But after installing the PCV "autotune" the bike which ran great before just runs that much better. I will probably leave the top end alone now. I did install andrews 54s earlier in the year. A good tune is unbelievable. I have had alot of dyno tunes over the yrs bikes ran good. Even ran this bike on a dyno. Butttt with this PC autotune it now runs great even starts easier. And mpg has went up so for from 38 give are take to 43-44 mpg just going to work. I am still working with the trims and it keeps getting better. I come home from work get out the lab top and load the trims. They are about done trimming at that point I am going to switch the autotune off and call the map done.

Just got my stage 1 with Thundermax TBW. Because of stinky weather I only have about 30 miles on her...

Nice and smooth at speed. Bike pulls noticeably harder 70 - 90 mph in sixth.
Idle hunting a little bit, that should go away as TM auto tunes.
My right leg thermometer says the bike is noticeably cooler now!

I will write a real review after I get some miles on her...

Sorry I didn't see this.
I just set it up running the stock engine with my 2/1 pipe and air cleaner. Been long enough I really don't remember much but it was as close to stock as I. Could set it with thus extras I had.
