awsome knob loving it , fast delivery !really satisfied! Thank you guys!

Greatest decision I’ve made for my 18 Civic SI. Power is really noticeable. Shipping was really fast and on point!

Coming from Hondata after all these years I was running the 6+ psi map and loved it but it was still missing something. In comes KTuner with TSP stage 1 and wow that’s what a car should feel like. Has just enough power when u need it and doesn’t sacrifice MPG! Amazing little tune that’s all u will ever need! Great value!

Great product , great company. When I received the Ktuner I wasn’t sure how to set up the tsp tune. Emailed the guys over at TSP and they assisted me right away! Car feels so much better with the tunes installed

Awesome!! Pretty smooth, I like it.

I waited 7 weeks for this exhaust. But I gotta say, I've owned quite a few cat back exhaust and this by far, has the best fitment and sound of all. Priced right as well. I love the extra details done to it. Thanks greddy, you never disappoint me. It was definitely worth the wait.

This product is awesome, feels great while driving aggressively.

Was previously running the dual 21.5 psi base map and it’s night and day. Would 100% recommend this to anyone who wants a little more zip.

A tune only really fixes livability on these cars.

Setup and flashing was super straightforward with a halfway decent windows laptop. TSP Stage 1 makes a very noticeable difference in power delivery on an otherwise bone-stock FC3. I've been running this tune for a month and have been pretty stoked in the canyons so far. Very consistent power. 🤘

If you have a 10gen civic , I would highly recommend the tsp tune . I took to long to buy it . Pull the trigger now don’t wait like me lol .

Easy to use. If you know what your doing. I Should have done this much sooner

Great product definitely needed on any 10th gen 💪💪

Awesome product from an amazing company. Highly recommended that anyone that is looking to order ktuner buys from TSP!

I try the Ktuner with standard map for about 1 year, than I decide to take the TSP stage 1 map, another world, really good job!

Very nice quality and can't wait to wear it to car shows to come! Fits exactly how I expected!

Honestly. the visual look of the ktuner v2 is beyond clean looking. You can customize it to your own liking, and at the same time have that extra piece of mind with the additional specs of how your car is running! Out of the box I flashed my car to the TSP stage 1, and man. No longer was I debating on moving to a different platform. It completely revitalized the car and made it a proper sports hatch paired with a intake/DP/exhaust. 5 stars doesn't speak loud enough!

Call this tune Emeril because it turned my Civic up to ANOTHER NOTCH. Bam!!!

The fit and form of this steering wheel should have came factory. Nonetheless, this is one of my favorite mods so far. The wheel has a nice, prominent 9-3 grip, thicker than the factory steering wheel and it exudes quality.

It’s amazing! Looks stock highly recommend getting it!

The Cobra CAI was my first mod I’ve wanted and thanks to TSP I was able to get it soon! Amazing quality and it sounds amazing! With the RACE MAF and there Race tune you could feel the power! Amazing service all the way around thanks to Corey! Will definitely order again from TSP!!

Its a great tune. Works well with my car. Its just from 4th to 6th gear, K.Con goes high at high RPM. It goes up to .83 at times on 4th to 6th at 5000+ RPM. It lowers though when I drive normally. (.49-.54) I have a K&N typhoon short ram and Im installing an exhaust today. Hopefully it makes the K.con lower on the higher gears. I always use 94 octane, no ethanol.

Fast problem free delivery... looks good, srill waiting on install so ill leave another review satisfied thus far

Installed them on my 18 si sedan. The drop is exactly as described. 1.7” front. 1.8” rear. Ride is great! Not bouncy at all and perfect for this chassis. I would definitely get the rear camber kit tho. I went with the spc and everything is at factory spec After alignment. You’ll love these! Two step also shipped these fast as heck. Quality product. Quality service.

Amazing!!!

TSP Stage 1 Tune for 2017+ Honda Civic Si

Pricey .. But worth it.

Delayed order but. Its worth the wait it came out good! What an awesome modification. 4/5 difficulty installing it. But its all g

I’m FBO running this tune on stock clutch no major slipping really makes the car feel so different . Raced an R , was at the passenger door the entire time up to 140. Civic Si 17

Install is a little tedious but worth it. It's a whole new car. The amount of confidence when shifting is worth it.

Great Protection

KTuner was delivered within 2 Days and the TSP 1 tune on the civic hatchback sport totally makes it feel like a different car!

Loving the Thermal R&D exhaust! Shipping delays due to covid was expected but shipped fast and FREE once product was back in stock! Thank you!!

Car shifts so much smoother

Good quality decals, but be prepared to be patient with lining up corners. Take your time and they look fantastic! Comes with a spare each so totally worth it!

this install wasn't that bad took about 3 hours with help from friends. Great sound and you feel the power with the tune!
