“Setup and flashing was super straightforward with a halfway decent windows laptop. TSP Stage 1 makes a very noticeable difference in power delivery on an otherwise bone-stock FC3. I've been running this tune for a month and have been pretty stoked in the canyons so far. Very consistent power.”
“The TSP stage one tune lives up to the hype. Transformed my Civic Si. The KTuner 1.2 is super easy to use and posed no problems when loading the tune into my ecu.
Two Step Performance shipped the product super fast and emailed me the TSP tune quickly so it was waiting in my inbox when the hardware arrived.”
“My ktuner came in damaged. Emailed Two Step Performance support and they were able to send me a new unit, which came in quickly as well. Awesome customer service! Will definitely purchase again from Two Step! Also, the Tsp stage 1 tune for my civic hatchback sport cvt is killer! Definitely better than the base-map from ktuner!”
