Just do it!

These shifter bushings will take a short time to break in, but once they have been broken in each shift feels so crisp. Install was pretty easy. I strongly recommend these for your car

Tune pulls very hard and smooth , you really feel the push of the torque when you go full throttle.

Best customer service! Keep it up TSP!

I ran the stage 1 tune for over two years and it was an amazing tune. This stage 1 plus is so much better. The car drives a lot smoother and I highly recommend this tune with the race maf intake.

I love how the car drives

So much better than the original tsp stage 1. Way more midrange and top end and very smooth drivability.

My car previously to add the tune I have the ktuner
Upgrade Intercooler cold air intake cobra and was already fast with this tsp tune is faster not to much but love Honda’s any way always been my favorite car in the world. Thank you for the tune

This was probably the best purchase I’ve made for my Civic. With the TSP tune it feels like a completely different car, and is way more fun to drive. The KTuner version 2 has also been stellar! I’m able to display just about anything I want in real time and I absolutely love it. Can’t say enough about the support from TSP they responded quick and with great information anytime I needed anything. The whole transaction has been a breeze from start to finish. You guys have a customer for life, thanks TSP!

Awsome

Overall very satisfied with the purchase of the KTuner. If your in the market for a tuner why not purchase one where you get a tune for free!! Overall good performance addition for my 19' Civic SI

Great radar, barely any false alerts

I feel the power 100% and i love it

Top Quality
