TSP stage 1 plus and k tuner are wonderful products. Really made my 2018 civic SI alive. I just smile so much while driving on this tune. K tuner is a well built product and highly recommend. The support from the tsp team is something else!

Worked as described.. quality part

The ktuner v2 is a beast!! The difference from stock to stage 1 is impressive but the stage 2 map is pretty crazy!! I just have a few bolt on's and the car feels completely different. I would highly recommend this product to anyone!!

Super easy install, all the bolts lined up properly. Some users mentioned they had to use a mallet/etc. to get them to fit, thankfully was not the case.
Might be placebo effect but the car feels more planted and less jittery in turns. Looks great with the gunmetal finish

No frills mount. Positions the Ktuner perfectly in the center console. It's at the optimum viewing angle, and is very secure.

Shipment was really fast and I'm very satisfied with the order, now my ktuner works like brand new with the new cable. 😀

Great product and super fast shipping.

Best product

Installed and now exhaust is not banging against bumper or heat shield over bumps anymore

Can’t be any more happier with the look of my hatchback now !!! Thanks to TSP/ Daniel for always take care of me and ship my parts really fast !!!

Made specific for the USR/P2R catless downpipes fits amazing. Made by ptp comes with springs and a loom of wire (didn't use). must have for USR/P2R catless downpipes.

Send it or go home, full l15 build

Exactly what I wanted sounds great

Excelente producto!!
