“I have a 2017 si and decided to go with the Ktuner V1.2 with the TSP stage 1 tune. If anyone wants to wake up the car, this is the way to go. 10/10 recommended. Fast shipping and fairly easy set up.
Thanks guys!”
“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!”
“Downloading the program would be a little confusing for some people but once you have it installed and programmed into your car, you'll be happy you bought this! Instantly noticed huge gains and love how you can see all the multiple gauges on the screen. Would highly recommend to anyone.”
“Purchased the Ktuner and their stage 1+ tune included. Product was shipped the next day and tune was sent to me same day! Extremely happy with the tune and the customer service!”
