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 fool proof. Just follow the instructions on the website, and enjoy your spicy Si.
Great experience as always! Derek is a great help as always. He jailbroke my ECU for me and shipped it back same day overnight! Flashpro arrived the day before but so I could get everything setup ahead of time so that worked out great too!
Recommend TwoStep and Derek to all my friends and family for all their needs!
Thank you guys! You're awesome!
Arrived really fast to PR and the product is phenomenal
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 hadnt received the Tune after two days, but Savanah got a hold of the help ticket and I had it within 45 minutes.
