    7. Calvin Tran (verified owner)

      Outstanding tune. Better fuel economy, less snatchy throttle (especially with throttle spacers), and smooth power throughout the rev range. Bike can idle in all gears now without stalling! A little more heat from the radiator though.

      The tune has unleashed the beast in my Speed Twin 1200. So quick and responsive and you better be tucked in when you shift gears and get on it. Phew!! Love it. My husband is so impressed he is going to get a tune from you for his Speed Triple.
