EVERYTHING I HOPED FOR!

Speaking as someone with no experience in the tuning world, the Flash V2 made tuning my Civic a breeze. TSP’s support was extremely helpful with getting my included tune to me, and answered any questions I might have. Plus, I really like how the V2 doubles as display.

MY CAR IS AWAKE NOW!

This tuner surely woke up my 2019 civic lx hatch and all turbo lag is gone. Time for some fun.

EASY MODE FOR MAX

PERFORMANCE

Everyone needs to do this to their car first before even thinking about any hardware mods. The increase in power is insane. Can be scary at first if you don't know what you're doing when all the lights on your dash start going off.

Ktuner V2 + TSP stage 1 = Quick

Definitely wasn’t disappointed with my Ktuner V2. The base 21 psi tune from Ktuner was already a game changer, but the TSP stage 1 tune gave it more of a kick which transforms the car into a little pocket rocket from stock. Pair it up with a PRL CAI and enjoy the louder turbski sounds.

FIRST GO FAST PART

I love the ktuner and tsp even more! I struggled to get started with my ktuner and was having some issues but tsp was quick to respond and help me in any way that they could, honestly helped more than ktuner themselves lol. Great product and customer service overall!!

SMALL YET POWERFUL

Doing wonders for my 10th gen Civic Si. Really is an amazing difference in every gear. Running TSP Stage1+. Does take a bit to setup though, especially if your PC doesn’t have high power USB to run the Ktuner and if you’ve never used one before, like me. Overall, TSP had the best deal and fastest shipping I could find.

WHAT OUR CUSTOMERS

ARE SAYING

REALLY WAKE THE CAR UP

The KTuner paired with the TSP Stage 1 tune really is the best bang for the buck. Wakes the car up like a mf. Customer service is also great. Had an issue where I hadn't received the Tune after two days, but Savanah got a hold of the help ticket and I had it within 45 mins.

David Collins

VERIFIED BUYER

Really fast and great product

I enjoy the throttle response, however, I wasn’t able to tune it to stage 2, not because it didn’t work but because if I do, the dual stage 2 or stage 1 tune, in sport mode, top end cuts out and triggers my check engine light. In eco mode, it’s jittery like it hops as if I were driving manual. Other than that, I love this product; feels pretty solid for a quick boost in throttle response.

MUST HAVE for 10th Gen Civic Si

Anyone that is afraid of bricking or hurting your engine/trans, rest assured. This tune is subtle but wakes up your car. Makes it feel so much better, better power, better acceleration, better shift feel. AND the install is almost foolproof. Just follow the instructions on the website, and enjoy your spicy Si.

Tired of Feeling Left Behind?

You’ve been there - watching others fly past, their cars roaring with power, while your ride just can’t keep up. The frustration builds every time someone talks about their latest upgrade or leaves you in the dust at a meet.

One Upgrade, Endless Respect

Then it happened. You installed the K-Tuner. That first pull was electrifying - smoother shifts, instant throttle response, and pure adrenaline. Suddenly, your car wasn’t just a way to get around. It was a statement.

Welcome to the Brotherhood

Now, you’re part of it. The nods at meets, the envy from friends, and the shared stories of late-night runs. It’s not just about speed - it’s about being part of a community that lives for the love of driving.

Civic 1.5 sport touring TSP tune

so I’ve had a ktuner and running the TSP tune for around a month now. This tune definitely brings the car to life, map 2 is the perfect map for street/highway and canyon runs. I’ve taken it through Angeles crest highway multiple times and it feels like a completely new car.

Love it

This is how the civic 1.5 non si should have came. I mainly drive in stage 1 but when I can I go in stage 2 and haven’t gone stage 3 yet. I can feel the power and torque upgrade and no turbo lag and love the power at lower gears instead of before put your foot on the pedal and their is a delay and then the power hits. Now it’s instant power.

Completely changed the car for better, highly recommended!

ktuner & base tune - 2L nonturbo civic 10th gen

pos: website is easy to navigate, fast shipping, base tune is nice with much improved throttle response & a little more horse power.
neg: not a user friendly process for 1st time users, but that might be all of them). no additional (more powerful) tunes available for non-turbos.

PRL Rear Motor Mount for 2025 Civic Si

I got this on a discount as a returned item but bought it anyways as PRL makes outstanding products. Rear motor mount came in good condition and installation was straight forward. Took about 35 minutes including a pry bar to flex the motor along and a dead blow hammer to get the motor mount fitted in. NVH is noticeable on start up but is barely there on idle and unnoticeable during driving.

Bien producto me encanto

great shifter upgrade!

Great product and upgrade for the FL5!! very crisp solid shifts. would recommend to anyone with 22+ civic.

Cheap but Worth it

Best thing for some extra piece of mind on items you order.
