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.
Its a decent bump in performance. Map 3 gives clutch slip for my civic si clutch if i wide open throttle. Otherwise its great. Ive been able to flash to tune and back to factory just fine.
Support was really helpful and responded quickly. Makes the car really fun to drive.
The clutch feels amazing and really smooth shifting and downshifting. You can tell the difference in weight immediately
