B. Dog ?

[DocDetonancour]

I have the power pup and am running on the performance mode (90 h. p. ). I have noticed if I use WOT before 2k on the tac the engine "cuts back". Is this turbo lag and is it to be expected with this box? thanks, Doc

I have a power pup. On the 90 hp setting the truck really moves from off idle on up. My software version is really early and I have a 305/555 engine. I couldn't tell what you had from your signature.

I have the same truck, but no injector upgrade. I also have a "later" date PUP. May have to call B. D. thanks, Doc

If you are using your stock lift pump you could be running out of fuel

I got the same problem with mine. Its an 05 (600) with the bullydog power pup,I also have the fass 150 fuel pump and just changed my filter and still does it. The fass keeps the fuel pressure at 22 lbs and when its wide open it dropd to 15 lbs. It only does it crusin down the highway when i hardly push the pedel. My brother has an 04. 5 with bullydog powerpup crazylarry program and it doesnt do it even with the stock lift pump. Any help on this would be real nice.
