Do you have yours coming on progressively on just all out once out the hole? Every truck is different but you seem to be one of the only one willing to share insight to get their ext cab pig moving out.
keep in mind get all you can out of the setup NA, thats the key even if you have to read the plugs NA, i always run race fuel at the track 109 in the fuel cell for motor, c16 in the stand alone for nitrous, iv'e pushed 38 degrees of timing NA then backed it back down to 35* 35 being optimum. i also run 13.5 AFR on the wideband NA, low pressure systems are the way to go, you can control the fuel pressure and rich and or lean issues, helps to dial in the nitrous easier if you ask me.
HP tuners you will need, here is where you will make the changes when you need to make changes your tuner wont be able to do it for you specially at the track or just plain not available, only changes i really made are in the timing and shifts and lockups, ( manual now so shifts and lockup is history ) during all this time reading plugs is a must and knowing and having the right plugs in the engine.
timing NA setup, get the fueling where the motor likes it along with timing, i increased mine 1* per run until it didnt show any gains up to 38* found out 35* was the sweet point for my NA seup, made several passes and logged everyone data is very important the more the merrier
then the nitrous, backed the timing down made a pass seen where we stood ( read plugs ) new set installed before run
fueling i started at 12lbs which was very rich, back it down a lb per run or as much i thought would be enough i ended up at 9.5-10 which in the end gave me a 12.8-13.0 AFR with nice looking plugs
