I'm going to advance my pump some but I believe I have a couple injectors going south on me. it hazes at idle and smokes pretty good which it didn't used to. I have new injectors from a ppump they are 5x.008 I know I'm stepping backwards, the cross sectional area is .000251 compared to .000380. Would I get better mileage with the smaller nozzles and would it burn better with 5 holes? Would I notice seat of the pants power loss with the smaller nozzles? I could try and repop the stock nozzles but I'm not sure if I will need new nozzles or not, I figure I could try theses 5 holers if nothing else.
I pulled a trailer back from Oklahoma and I got 13mpg going down with an empty trailer at 70mph 2-2100 rpm and coming back I got 12.5 with 6-6.5k pounds on the trailer (not sure what the trailer weighs) maybe 8-10k total. I was alittle disappointed as I don't think I should have been under 15 and defiantly shouldn't have been under with an empty trailer.
