I bought some 42lb direct swap injectors for my truck and apparently they are not big enough for my set up. What size should I get if i want to run 14lbs of boost? I dont want to have to waste money on injectors again.

 

I would get the 60#'s. I picked them up for my 6.0 swap. Nelson has them, or you can find them on ebay. Whippled can fix you up w/ some plug and play adapters for the injectors.

What method are you using to determine the 42's are too small? I don't doubt they are just curious....I would think 60's a minimum....

 

X2....

 

got my 60's from a guy off tech.

I will be using plug n play 62lb injectors for my build. I just started a post about them here: https://www.performancetrucks.net/fo...42#post3898642

 

do you wanna sell your 42lb ones?

 

I just started back to the tunning of this truck. I havnt done anything with it for over 8 months. I did a log today and hit about 6lbs of boost and at 4800 rpm my inj duty was 105%. If 60s are a min. should I go with something around 80's?

 

Oh and yes I would like to get rid of these 42's they have only about 250 miles on them.
