I dont spray my truck, but Im gonna hit it with a 100 or 125 shot next weekend, and a 125, or 150 two weekends after that. Is there anything that I need to do besides bump the timing down?? Also, how much timing should I remove? I think Im running about 36* right now

I'm not familiar with the "normal" timing for your truck, but alot of guys will drop it 1-2*/50hp. Not tuning related per se, but I'd change to a colder plug and run the proper safety devices as well if you're not already. (wot switch, window switch, fpss, etc).

make sure you wont hit the rev limiter.. its a fuel cut limiter, and cutting fuel on nitrous is a no-no.

i wouldnt pull out timing unless i was spraying a larger shot.... assuming you're running the proper nitrous plugs and all, just do it like a bolt on kit.... no timing changes.

if your engine is modified, check your WOT AFR with a wideband before you spray.. you dont want to be lean before you start spraying..

i'm in the same boat about the tuning for nitrous, wanting to know what all to tune for a nitrous shot (150)

You can run the 150 shot without pulling any timing. here is how i tuned for nitrous.

I tuned it NA to a AFR of 13.0 @WOT, easy, kept stock timimg tables too. Then just threw on 62 n2o jet and a 33 fuel jet. My AFR on the juice is low 12's at mid rpm's to low 11's at the high rpm's. Plenty safe.
There is no need to pull timing on a shot of that size. Just be sure to have enough fuel and dont activiate the nitrous till at least 2800 rpm's
