Can is use 42# injectors on a truck with no internal engine mods as long as its tuned for them?Just LT's w/ ory,exhaust,CAI,ported tb,and 160 stat?
Will do heads/cam/intake one day and eventually stroker when the engine dies.
Ive read the stockers are to small even on stock trucks much less when u start modifying them.
42# will be plenty for what u need...
Agree with DBRODS. 42 pounders will be plenty. Just look at my sig and I'm only running my injectors at 84% duty cycle.
my 42's are only at 69% also...
My stockers with hardly any mods are in the high 80's to low 90's before the 1-2 so get what you're gonna need in the future now.
Stupid question that I could probably find the answer to pretty quickly, but...
What's the stock LS truck injector size?
24lbs. I believe.Quote:

Too small. I have hardly any mods and I'm in the 90% range.
Because the flex fuel ones like mine are like 32-34 pounds.
Yes, you can use 42's on a bone stock truck if you wanted too as long as your pcm is tuned for them.Quote:
