Ordered some PW injectors today...........

[V6power87]

I was wondering how much more power I will get with the stock fuel pump settings? Do I need a pyro? Right now I have 16-17 psi boost, how much more will I get with the bigger Power Wagons? Have any of you guys gotten worse fuel economy with bigger injectors? I ask a lot of questions don't I?!!

I don't know about the boost - but I did not loose any with PW injectors, and perhaps gained a bit. Never under 19, never over 21mpg.

Personally I would get a Pyro - especially if you are doing a fair amount of towing. As far as economy, well that depends on how much control that you have over your right foot #ad

. Most of us have a tendency of using the extra power because it is available #ad

I went from 15 lbs of boost to about 26. A general rule of thumb is 10hp/per lb of boost, and I beleive CrewCab dyno'd his rig with this sorta setup and got around 240 hp,610 ft/lbs. I think I lost 1. 5 mpg, but it may be from lower cetane winter fuel, I made the injector switch in Dec.
