you feel a big crazy different once you get stage 2 and some beautiful tasty e85
This tune is totally tits, huge difference over stock
I’m impressed. I absolutely love the upgrade. The power. the torque. Great job tsp. You should do a stage 3 flex fuel fbo! 🙏
I love the tune. I drove around with the tsp stage 1 tune for the past couple months which I had a lot of fun with. Let’s see how long this stock clutch holds up.
this by far it the best off the shelf tune you can order

Map 3: 19 psi normal, custom boost level "Sport" mode, Improved Turbocharger Response II
Factory boost level in "Map 1" allows for easy "valet" mode when the KTuner unit is unplugged from the car!
Premium fuel (91 or 93 octane) is REQUIRED for gasoline use. Ethanol content should be limited to 30-40% when blending E85 with gasoline. (35% recommended)
An aftermarket clutch is STRONGLY recommended, as the stock clutch will not survive this torque level.
This tune is designed only for use with the factory turbocharger and is not suitable for used with upgraded turbochargers.
Dyno testing performed on a 2017 Civic Si with ClutchMasters FX400 and KTuner FlexFuel converter setup (stock airbox/filter, stock downpipe/front pipe, stock exhaust, stock intercooler, etc). More power/torque can be seen with better cooling and higher flow bolt-on parts.
Suitable for use with the factory intake or a QUALITY aftermarket intake that keep fuel trims in check such as the PRL Motorsports Cobra. Aftermarket downpipes are also fine.
