My 114 Heritage with stage 2 and SE tuner runs flawlessly. I’ve tried several different pipes for sound with zero issues, no matter how open. Never any decel pop. I’ve been very happy with the tuner’s performance. I agree to take it back to the dealer.

The moment the extended warranty on my ‘18 Deluxe runs out, I’m replacing the Street Cannons and OEM tuner on it with V&H Straight Shots and a FP3. I am fully expecting some decel pop when I do that, but it’s super easy to compensate for that with a FP3.
