I have been running 370s from new era that have the corrected spray pattern and I do not have enough fuel, i have my afc let off all the way and ive tried it with the foot out. When go hard with her, the exhaust cleans right up and I have no egt problems. I know i need more fuel, is buying new injectors like some from DDP the answer??

 

oh yea, and fuel pressure stays over 40 psi. any help would be appreciated.

 

Can try bigger DV's if you want, but I would go with bigger injectors. Those are only 90hp injectors. Get some 140+ hp sticks. What kind of power are you making? Boost?

 

I have never dynoed it. It makes 70 psi of boost. I didnt know that the 370s were only a 90 hp injector. So you think my limiting factor is my injectors as opposed to my DVs?

 

you injectors are to small. the 191's are fine try some bigger sticks to take advantage of those twins also whats your timing at

 

My twins clean up 140hp sticks with 181dvs with no problem at all. the 191's will give you more fuel than what I have. I'd go with a 5x .014 or .016 depending on what you use the truck for.

 

cumminsfreak - my timing is around 16*

BigErksG2 - I just use the truck for a street machine, i dont do any towing and do not care about fuel milage.

its not my daily driver, i just want it to be fun and quick.

thanks for all the input, i learn so much from this site

 

are there less expensive injectors out there other than DDPs. It is hard to spend a grand on injectors.

 

get ahold of JL machine I'll Get ya the number later just PM me to remind me

 

thanks, I will try him out.

 

I would look at SDX (Southern Diesel Extreme). 140hp injectors for $500. Top notch stuff from what I've heard.
