Weston told me the numbers but I guess I never put together that it was you.

Good post Andy.

The pump in my truck is a built one.

It has been outfitted with a different cam and different barrels and plungers.

Bigger injection lines on a dyno will lower your hp number,I have done that already.The .093's are better than a set of .120's which will really kill the top end charge on a dyno.I am convinced that it has to do with the larger injector lines retarding the timing a tad as the pump then works a but more to keep them full.I would like to have a billet front cover and adjustable timing gear to play with the injector lines some as I think that gowing to the larger lines and a tad more timing would net me the smae HP results.In a application where you are staying at WOT and at max fueling then I would say the bigger lines would benefit you with keeping the supply high for the engines demand.In a street application where you spend most of your time just barely using the pumps capabilities the bigger lines make daily driving tough and keep in mind I do daily drive mine so the big lines lie on my shelf.

The DV's in my pump are not full cuts either,they are high flows.The pump was done on the stand with them and I have 500cc's of flow and only pick up 75cc's with full cuts.The issue here is when you go to the full cuts it will kill the low end driving daily as it wants to put the fire out.I can already blacken the daylight with what I ahve and feel no need for the bigger DV"s that should only be used for all out competition.
