Default 12.8@104

Took the truck out for the first time after getting it done. I wanted 12's so im pretty happy with it considering im still fighting some issues. Truck would not shift into 3rd so i was on the limiter at the end of the track. Got it fixed on the last run but had a horrible 60' so it didnt go any quicker

10-11lbs of boost
16 deg of timing
9gph of water meth coming on at 6psi, truck is hella rich on the converter so i couldnt leave very hard or it would just bog, my snow pump i think is shitting out and leaking even when its off so i think that was alot of my issue

overall im pretty happy being i did all the work and tuning myself( with the help of a few others) I know theres alot of improvement in the tuning but so far have not found a reputable tuner to help

left lane

Id say 450. My crew cab LBZ Dmax ran 13.1@102 with a tune that was around 480hp and we both know how much heavier those trucks are than yours. Congrats on the 12.

My 05 crew cab I had, 2wd when I had the 5.3 and vortech centi blower would run 12.8s at 104-105. At that time it dynoed 459rwhp and 489rwtq. I would think you would be closer to that then 400rwhp. 8th mile was 8.30 at 86mph with a 2.0 60ft

lol 4wd, nitto 420 tires. Didnt spin or hop just my tuning is off so if i tried to leave in boost it got rich and would bog. the 1.8 i maybe left at 1lb

im having water meth issues to i think thats alot of my issue with spooling and going really rich

Also im not locking converter, so i know im losing there, i think with a 1.7 60' and tuning a little better with around 12lbs of boost id prob be in the 12.50@108 range. Not bad for a heavy 4wd pig. Ill be first to admit my tuning skills are pretty sub par but i think i did pretty decent
