[QUOTE="Sielmo, post: 15572337, member: 170856"] Just did the install myself to factory vice degreeing the cams. Added L&M low vacuum booster and have surge issues. Discussed with JDM and my tune idle was bumped to 850rpm. Also adjusted the TB idle adjustment screw 3/4 turn to the right. Still have the surging throttle decay, sometimes as much as 500 to 750 rpm, usually while coasting . Any suggestions? Sent from my SM-G930V using Tapatalk [/QUOTE]
