Working on a buddies truck, this one has had some issues on both the mechanical end and the tuning end (my first speed density tune)
82 c10
06 L33, ls6 cam, 1X cam sensor setup
turbo 350 trans
The issue we are having is its not getting much timing at WOT, maybe 10-15* and its a dog. I can command 25 and it pulls hard and gets zero knock. I just cant seem to figure out why we are not getting much timing. the corresponding cell of the spark map call for 25-30ish* when we see 10-15 commanded advance. Not seeing any knock, IAT is good, coolant temp is good. i dont see any reasons for it to be pulling timing.
with this being my first speed density tune im still learning, he also still has a few kinks to work out. we are getting a p0343 cam sensor code and backfires on start up, likely from no cam signal, also he is not running a VSS.
any input on the timing issue would be welcomed
attached is the current tune and a short log file.
