kinda self explanitory, before i put bigger injectors in my truck would start to miss at around 2600 rpm, now with 140hp injectors it starts missing at only 2300 rpm, oh ya and it was re-timed by toxic diesel, so i am confused

 

Are you still running 131 DV's?

 

im shure of it cause they are stock, i read a similar post on here and the 131 could only handle so much, but im trying to spend as little as i can these days.....

 

I think you'll have to step up to 181's to cure it. Maybe find someone local who would be willing to pull theirs so you can test them. Atleast you will know if that will fix it without spending anything but time.

 

i heard when you upgrade the delivery valves you dont reuse the old washer on the bottom, is this true?
