2014 Triumph America with an air filter, emgo cocktail shakers, removed sai and o2 sensors. Easy to follow instructions are given and must be followed to a tee.

This bike has never run better. After 700 miles I pulled the spark plugs and they are not fouling. The best possible outcome and much more affordable than having it dyno tuned.

Wow, what a difference. Transformed my 2015 Speedmaster from a stuttering, jerky ill running motorcycle, to a smooth running, great sounding, beast.

I stupidly downloaded the wrong tune originally, but Mike had it sorted out in just a couple of emails and resent the correct tune.

Great customer service.

Thanks again.

Bonnie America 2009 - O2 & AI retired, Breathe Intake Cover installed, Foran short, open pipes - America Performance Tune 3.

I had no end of disappointment with the America - snatchy throttle response, poor torque and stalling in very nasty situations. As for downhill popping, this thing could have popped for Australia!

In stalled the Breathe, removed O2 & AI and installed the TTP Tune 3 - Seriously Brill! Mid and high range torque is great, pulls like a bull in springtime. The stalling is gone (thank f**k). Downhill it just purrs and the engine brake does its job. I have traveled a thousand kms since the changes and I love it. You will not regret this tune!

A word on the guys at TTP - Service was excellent. I stuffed up my choice of tune (seniors moment) and they were awesome in getting me straight. Thanks TTP!

O2 sensors removed sai removed, tune 3
remap. Sent mine to TTP to be mapped. brilliant service, back by return post. Bike is now very smooth with no snatchy throttle. No popping exhaust (reverse cone megas) and strong acceleration. Much more enjoyable to ride.

From the moment I started the bike I could hear the difference in how the bike ran. The sound was impressive and mean.
However the moment rubber met road I was riding a brand new bike. Smooth as silk acceleration and fantastic power all the way into the shift. Accelerating to pass vehicles no longer required a downshift as all the power i needed was readily available with the twist of the throttle. Highly recommended.

Got my ECU back quickly. Removed the SAI and 02 sensors. Added the TTP Breathe Cover and D&D megaphones. The bike runs like a different motorcycle. No back pop on deceleration and much smoother through the gears with a noticeable increase in power. Very pleased!

150 miles today in 20 C weather, 2010 Speedmaster, D&D Boss Slipons, TTP Breathe, DNA, O2 and SAI in a drawer.

Right away, most noticeable was smoothness at very low power/speed. Very nice in parking lots, etc. for EFI, you get the "instant on" feel, but not snatchy and very controllable now. Nicely done.

Did several max effort accelerations, shifting at 7000rpm, all the way to 100mph. I can definitely feel the added 15% horsepower and increased torque. Very enjoyable high speed cornering in 4th gear with revs 5-6000, able to engine brake and excellerate smartly. Sustained cruising at 80-90 mph, engine feels and sounds strong. Again, very nicely done.
