To begin this off I am entirely new to gen V tuning, I am very green with most of this torque based tuning so I apologize if some of my tables look like they have been on the beaches of Normandy. I've mostly worked with Gen III cars and recently a customer brought me this escalade with a DOD failure, So I fixed the issues and installed a BTR Stage 3 Truck Cam and it drives fine but it will not start without giving any throttle input . Most of the time it is pretty difficult to get started, once started it will idle for 20-45 seconds then it will start surging until it stalls unless put in gear. it will occasionally stall at low speeds and almost always after heavy breaking. I have changed just about every parameter I Can and nothing seems to fix it other than removing the vacuum line to the valley cover, Once that vacuum line is removed it runs fine. help would be appreciated. I will attach 2 datalogs and the tune along with a stock tune.2015 Escalade l86 BTR Stage 3 Truck cam idle Surge, Stall and no start without throttle.hpt2015 escalade btr stg3 2.hpl2015 Escalade l86 BTR Stage 3 Truck cam idle Surge, Stall and no start without throttle.hpl
