It’s not bad to play with other Harley Davidson tuner options. It seems to get the job done too…in fact, pretty well!

Don’t get me wrong, it’s a high-quality one that improves the performance of your HD. Yes, it’s inexpensive but not ‘cheap’. You can save a lot of money skipping the Dyno-tune sessions. Besides, Dynojet stands behind their tuners for a very reasonable period of time. Your investment is safe!

The reason is pretty simple; you can install it yourself. It comes with the handlebar mount to make the installation easy. Just watch some YouTube videos and you can do it yourself.

But how does it help to improve the performance of your bike? Every time you change any item of your bike as a part of improvement, it tunes your bike so that the bike can run correctly. Many bike owners confirmed that it has made a huge difference in the performance of their bikes.

ThunderMax Harley Tuner

It’s something like people have expressed their regrets for not installing it years ago. By now, you do know what an auto tuner can do, right? Apart from the V&H, very few brands like ThunderMax are doing fine. It’s maybe the only tuner to meet your Throttle-By-Wire Harley.

Some motorbike riders have installed and found performance improvement instantly.

Most people have described it as the flat out bad-ass! Before installing it, the feeling was like they were running their bikes on the emergency brakes. But after installing it, they thundered seeing its amazing power. You will notice an improvement in gas mileage too.

If your bike is not running great or as it is supposed to, it’s time to get a tuner for it. Just with the pre-load map, you will notice significant improvement. It’s in the market for a very few time, but it seems it’s doing great among Harley enthusiasts. Many have confirmed its flawless operations for years!

Let’s talk about its wide-open 02 sensors. The stock 02 sensors of Harley are narrowband (12 mm) where Thundermax comes with an 18 mm wide band to allow rich and lean adjustments.

So, what’s the benefit of wide-band sensors? Well, every time you ride your bike, it automatically adjusts the fuel to air ratios. FYI: You will find the same sensor in a Dynojet dynamometer tuner too.

It satisfies the specific needs of a wide variety of performance upgrades of your Harley easily and hassle-free. From cool operating temps to quick throttle response, it ensures increased power of your bike too. Every time you add cams or change the pipes, just download a new map and you are done!

I strongly recommend contacting their tech support to get the full benefits.

Besides, you can download the updated firmware, maps, software anytime you want too.

The first good thing is you can use this tuner with the factory 02 sensors. It works just fine with the stock bike. And it fits all HD with 4-pin connectors like ’07 – ‘10 Softail FXST, FLST, ’07 – ‘13 Touring FLH, FLT ’07 – ‘11 Dyna, ’07 – ‘13 Sportster XL.

But the most important thing for you to ensure is that your bike has 4-pin connectors before you make any purchase. Once you got the right one, install it and you will see the magic yourself.

For added tuning precision, the Auto-tune feature is just awesome. It may be for different grades of fuel or for some very unique components – the auto-tune feature will add another layer of precision tuning for the improvements.

Vance & Hines have developed a vast library of calibrations. You can download all the upgrades to re-calibrate the engine parameters and get a custom mapping for the exhaust systems.
