Hi new to Tuning and I have a couple questions. first when trying to start cold it cranks and backfires i stop cranking and go back to cranking and it fires right up. I read a few post where it was the Cam sensor. I put a new one in and still same issue. I checked the wiring. I have 12 going to the Cam sensor with the key on. I have been following Rinkrat456 idle guide. it idles decent, surges a little up to I cut in the LTFM after doing the Idle airflow. then it runs a little rough. can someone take a look at my tune and see if there is something they see and point me in the right direction.
