i would def get a tune tho

 

you run 87 in your truck? if so the timing is already low for a 100 shot anyway, put some TR6s in and 93 octane and spray the bitch, youll be fine!

this is taken into concideration no tune has been done to the truck, 100% stock!!

 

if you do not plan to mess with the tuning stick with a 100 shot. run 93 octane to be extra safe. if you have the good tools to tune and watch the plugs closely, ive heard of people putting 300 shots through a stock bottom end. the tune must be SPOT ON at that point.

 

it does hit hard on the 150

 

after my fuel pump install and new trans goes in i plan on bumping it to a 200, mine is a home made nozzle kit mounted into a throttle body spacer so its a home made plate

 

It's only as safe as you make it.

 

I had mispoke .. Im definitely getting tuned no matter what shot i run (100 or 150) but the kit is good up to 400 from nitrous express but im never hitting it that big(on stock pistons n what nots anyway) .. Max on stock motor with a tune was more what i was meaning lol i know afta i get it n hit the 100 tuned im gunna want 150 lol
