    17' Truck Norris 5.7 Idle Surge and TPS issue

    I have been working on my truck that I installed the BTR Truck Norris Cam for the 5.7 and it has been a fun journey with the install and now trying to get it to run how I want to. I have been working on VE for a little bit to get it close so I can drive it. With the current tune it drives decent, pretty smooth for during driving, getting an average of 16mpg. I have a few hiccups I'm trying to work through, but I haven't been able to get them resolved. There is a surge in idle while in gear that is about 200-300 rpm sweep and it rocks the truck pretty good. Also I noticed this evening that the throttle isn't opening past 76 percent. If anyone could point me in the right direction I'd be grateful.
