I had purchased a ktuner through tsp because my buddy had told me about the free tune with the purchase of a ktuner so I went ahead and purchased it and I ended up having a little bit of trouble getting the stage 1 tune so thanks to the help of Corey I was able to get and upload the tune and it’s unlocked so much potential since, thanks two step performance looking forward to doing more business in the future.

Great support feedback. The tune is worth every dollar.

This intake is amazing! The quality of the hardware is great and the install is easy, once you get the bottom portion of the stock intake off. The bottom portion of the stock intake is a nightmare to take off. I managed to take it off from the bottom of the vehicle with the removal or the two brackets that hold the stock one in place.

The performance for the CVT Sedan is great, paired with the TSP Stage 1 Tune. The sound amazing. Give it gas, let off and you got the BOV sound :) I definitely recommend this product to anyone looking to get a little more performance & great sound for their 10th gen civic, whether it’s a CVT or manual!

This is a wonderful Stage 1 tune! I have a 2020 Civic Si that's completely stock, so this really wakes up the car. It makes daily driving a lot more enjoyable by giving you more refined power and torque. Honestly, the car should've came like this from factory!

All I can say is wow

Nice smooth power curve, feels like a cleaner burn of the fuel.

The car feel much better ! Map 3 is awsome :)

I have a 2018 Civic EX-T Hatchback CVT Transmission and I recently just purchased KTuner V2 w/ TSP Stage 1 Tune. As far as my car goes I’m full stock for now other than a Mishimoto Air Intake. This product really woke my car up and has made me look at my car in a completely different way. All the reviews are true, it pulls, it wakes the car up, the horse power is completely different in a better way and super noticeable way. At first I tried the dual basemaps & loved those! I was able to tweak them to my liking & go on the fly. Then the next day I uploaded the Stage 1 tune and was highly impressed and how strong but smooth it is. I was able to go for a good drive on some good roads and test it out. The TSP Stage 1 Tune is how the car should’ve came from the factory. Once you’re on this tune you’ll be mad at Honda for their factory tune if you’re anything like me. Now outside of the product a little bit, I spoke to Corey the whole time about my order, about the tune and he was very responsive, very helpful, and also showed gratitude as well. The customer service is awesome from what I have experienced! I’m excited to add my PRL Cobra Intake Race MAF as well as my PRL FP/DP combo with the Blox Racing exhaust. At that point I think the tune will just be even better than what I have experienced. If anyone asked I’ll always mention Two Step Performance!

Wow. This tune definitely wakes up the car and it's a well spent $80. I have been using the Ktuner base map but the TSP tune is much smoother and more responsive. Paired with other bolt ons and you can't go wrong with this upgrade! So happy with my purchase!

Parts are satisfactory, customer service from tsp is amazing. Frontpipe/downpipe makes a huge difference is performance and sound. Thank you!

First mod and it is by far night and day!

Deleted clutch delay valve and added braided clutch line for improved engagement and feel.

Amazing tune, it really wakes the 10th gen Si up. This is definitely the best bang for you buck mod you can buy!

Great tune. Feels much better than KTuner base maps.

Makes you wanna turn down your music because it sounds so good. Plus you get some gains in HP (RACE MAF will need a tune). Overall amazing product, easy install.. except that one bolt under the car (take off skid plate).

Noticable difference over the basemap from ktuner. TSP didnt read my comments of keeping map 3 as default map when starting the car every time though. Wished that was a option but overall great tune for the money!

The month long wait cause of the backorder was totally worth it. The PRL downpipe and Cobra CAI are awesome and the TSP stage 1 tune is amazing.

Got here fast and easy setup. Definitely wakes up the civic si

Came within the time said and once installed wow the difference in the car, I mean why not come out the dealer with a ktuner on it.

So much smoother then the base tunes ktuner comes with. I highly recommend getting this!

And more

You can definitely feel a stronger push as opposed to the Starter 21 or Stage 2. The vehicle seems to breath better and for longer as you accelerate. Might I add that in just regular driving that engine operation is very smooth. I only have an Upgraded IC and Drop-in air filter (CVT Model) and this tune is most impressive. For the addt’l $80 it is worth just as much as a custom tune on pump gas hands down. If you don’t have it and are on the stock turbo GET IT 👌
If using “Adv VSA”, keep the setting on LIGHT it is plenty good there and will save you from cooking the CAT.

Derek has done an excellent job with the tune. He’s very knowledgeable and I am more than happy with the tune.

I have a 2019 Civic Hatchback Sport Touring. The difference after the flash is night and day. So much more response out of the CVT and hasn't really changed the MPG. This is how the car should come out of factory! A must buy!

awesome sound on the intake, loud enough not to get bov

Shipping was fast, customer service is fantastic! Really woke my 2018 Si up. It’s so much more fun to drive! Thank you TSP! We’ll be doing more business in the future!

i live in the UK and i have always contacted Corey at TSP to hook me up with new upgrades for my car. his service and responses are outstanding. i will always use their business for any upgrades or queries i have. TSP have fantastic range of products and the shipping process is the easiest i have ever experienced. very pleased with my latest product. will definitely be using these again in the future.

Must have if you are looking to get Ktuner or Flashpro. The tune has allowed my 2020 Civic si to keep up with a 2009 Cobalt SS and 2013 Focus ST (so far) which you can watch here: https://www.youtube.com/channel/UCXOXrt9Xk-GtT8G3juBd6jA?view_as=subscriber

Love the ktuner. The TSP map is by far the best one on market

First CAI that I have purchased and wow does this really wake the car up. Pair this intake with a Race MAF and the TSP Stage 1 tune and you'll be grinning ear to ear with every drive. Not to mention the awesome sound!

Not only are you getting an awesome tuner, but you are getting what I believe is the best tune that can be bought besides a custom tune. V2 makes it super simple for viewing parameters and flashing your car from different tunes when needed. TSP stage 1 tune brings out tons of hidden power compared to the stock and even basemap tunes. A must have for the 10th gen platform.

Was really easy process and fast delivery.

Amazing product. With the stage 1 tune the si drives like an entirely different car how a si should drive. Eliminated the annoying rev hang and much more power in the mid and upper ranges.

This product is very easy to use and works great! It adds a nice little punch to the car and makes it really fun to drive! I also got slightly better MPG with the TSP Stage 1 tune. The difference is day & night and the on fly switching works flawlessly!

i notice the power difference right off the bat and i love it 😆 stage 2 coming soon
