[QUOTE="TurboTJ, post: 1427282, member: 33074"] I installed a Cobb stage 1 91 octane map and now there is engine knock. I can hear it when accelerating at wide open throttle and I log over 7 counts of engine knock on cylinder 3. Has anyone else encountered this? Does anyone else monitor knock after installing the Cobb? it’s a 2019. [/QUOTE]
