hoping to find some answers.
Ive got a 2015 denali 6.2
recently had a lifter kill its self and bent a pushrod. so i decided to upgrade the cam i wanted.
I installed a BTR stage 3, 4 degree phaser lockout, springs, dod delete ect ect.
I already had KNN cia and 1 3/4 long tubes with no cats.
my tuner comes highly recommended for the gen v engines. i dont feel hes missing anything.
however we cannot get it to idle at all. we went through 5 revisions of the tune. after the first 2 we found an issue on my end. i had a bad plug wire. so i replaced the entire set and all new plugs aswell. im checking temps at all ports and i have equal temps. after the 5th revision he asked for me to check my timing. so over the weekend i pulled the front cover and oil pan. ill note that i did not pull the oil pan to install the cam. my timing was dead on after taking it back apart. I also decided to check i did the phaser lockout correct. i did see that it wasnt in the spot that everyone says to put it in. so i corrected that. after getting it all back together it still wont idle. im just completely lost. all seals other than the throttle body seal are all new. rear main will be installed when i get my new torque converter in. ill include my log with the most recent tune.
tune 6 log after cheching timing.hpl
