ok changed the injectors to rv275s from dap and mileage got a little worse:banghead: was running 5x5 than tried 3x5 now trying 2x5 the comp is tapped maybe time to untap but ill wait and see how this tank reacts went from about 15 to about 13:banghead:

No need to untap the comp, level 1 and 2 are just like no tap. I get best mileage on 2x5 though. There has to be something wrong with the truck. What size were the DAP injectors? Boost leaks, cel on?

no cel dont think i got a boost leak maybe my right foot was to heavy:lol: really concentrating now on the foot thing with this tank i ordered rv 275s hope thats what he gave me

Oh, I read wrong, thought you went from dap injectors to new rv275's. Hmm... never heard anyone loose mpg before. Hows it runnin?

sorry if i wasnt to clear i went from stock to rv275s the trucks running real smooth strong im really gonna watch my right foot this tank though but its hard you know:lmao:

You went with DAP RV275 - they are cheap chinese knockoff junk. . . . *GOTCHYA* That's weird - as asked how are they running ? Start fine ? No fuel leaks back of head ? No Boost leaks ???? I know shouldn't be injector related ...... but you know No codes ? Worst case ping DAP (Jacob) and see if he can switch you out to another set ....... very rarely they get and issue like all builders ........... hes normally awesome about that kind of thing ..... definitely call him

Would it matter who he got them from, or are there other makers besides bosch. I got my RV275's new in bosch boxes. The one guy said chinese?, so that would mean none bosch injectors? I gave up on mileage, i just drive, the scan gauge says 17-18, im good with that, i drive on 5x5, feels good, getting ready to put my 16's back on in a couple months for winter i will see if mileage changes.

How much bigger are the rv275 injectors than stock? I am running 100hp injectors with a stock turbo and my egt's are through the roof. I was wondering if it would be worth it for me to go to something a little smaller in injector size. I am not meaning to hijack but it seems like a good thread to ask this on.

about 30-40hp.100HP is a nice fueling level if you have the tranny and turbo (s300/57-62 mm) to go with it else - yes rv275 is a good balance for stock turbo tranny.

Yes RV275 and comp on 5x5 and towing 10k 5er, never went over 1k on egt, and cruising was around 900 at 65mph.

Wow !! I would kill for those egt's. empty, cruising 60 mph on flat ground, I average about 800-900 degrees. I do have a 6 spd with 4.10's and I know that cant help but i gotta do something to get the temp down. It makes towing and hauling not very fun.

I beleive DAP has both Bosch rv275 and a cheaper rv 275. He did when I first started looking at them. They were cheap. But for no more than what he gets for the Bosch, why buy cheap.

True, i bought new bosch, no worries about how they will work.
