TSP upgrade tune

I had the TSP 1 tune for about six months and was great. Found out about the upgrade so i have it a shot and it feels a lot better. The first one was great the upgrade is even greater. I like how it reduced the vibration from the rmm. Overall great tune made the car run smoother and feels faster!

Podium Oil Cap for Hondas / Acuras

Great quality

Acuity has great quality products made to perfection. Fits really nice and looks great! Also thanks TSP for great customer service and fast shipping!

Great Pedal Adjustment

The pedal is moved much closer to the driver and takes a lot of getting used to. Installation was easy and straightforward. I installed this on a 2019 Accord and it fits just fine.

Great Clutch Kit

As always, TSP was on point throughout the entire purchase process. Just installed it over the weekend and looking forward to a much better clutch compared to OEM on ‘19 Civic SI.

K tuner and TSP stage 1 plus

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!

Fit was excellent

Worked as described.. quality part

Ktuner V2 for the win!!!

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!!

DC Strut Bar

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.

Brought the car to life!!!

Purchased the KTuner v1.2 over the v2 to save some money and I don't regret my decision at all. I had an old android phone laying around so I hooked up to wifi, downloaded tuner view, and I leave that phone in my car to use as my "screen". TSP customer service was amazing, at first the stage one tune was not sent to me, but an email and about an hour later i had it in my inbox. I paired the Ktuner with a 27won race maf cai as the first mods to my 2020 si and i cant imagine driving without it now! The tune is amazing, throttle response is amazing, rev hang is gone, launch control is so much fun, map switching is seamless. Shipping was extremely fast. Love the product, love the tune, loved the customer service! Ill be purchasing future mods from TSP for sure!

Great Product! But Costumer service was on point.

I’m definitely doing some more business with TwoStep Performance again! Totally recommend.

K-Tuner v2

Ever since I plugged it in my car I haven’t taken the tune off unless I’m with my parents but it’s fascinating how a tiny touchscreen can add so much whp and torque to my civic Thank you for giving my the chance to buy one from y’all and I will be getting more later down the line!


The street model is a perfect feel of firmness throughout the driveline for a street vehicle that you want to make feel more sporty. It does its job of preventing the engine from torquing and stretching the shift linkage on the 6 speed manual. Finding gears feels more reliable at redline.
