P-pump is the ultimate answer to the 24 valve VP problems. Look at all the streetable 12v's out there. You just have to learn how to control your foot and adjust the pump to meet your requirements, either racing or daily driving. Granted its not going to be as simple as pushing the button on your edge comp, or even changing smarty softwares, but if you want your truck running down the road 365 days a year, a p-pump with a mechanical lift pump is the answer. Yes, virginia, if you're gonna do it, do it right and swap cams for the lift pump lobe at the same time as the p-pump.

 

yeah id go with the p-pump if you have time to down your truck for a little bit, but if that isnt a possibility id go with the Hot Rod VP

 

well, i dynoed today and it ran great!! so maybe its not going out, bad fuel maybe???

 

hey dukeboy do you run any additives in yuor fuel?? i started running additives in mine and with the cetane boost it started running better and got a little better mileage. ULSD fuel sucks @$$ need to go back to the 500ppm fuel that was the goos stuff

^^ good

 

i ran 2 cycle and half a quart of cetane boost in it this time, things style lopes alot at idle, maybe previous owner installed different cam or something else that could make it lope like it does, but it dynoed at 450 hp and 1172 ft lbs

 

You ever adjusted the valves?

 

i havent, unless daves diesel did when the previous owner had it in there for the injector swap

i maxed the redline and then backed out.

 

I'd try adjusting the valves. When they did the injectors, unless you asked, they more then likely did not adjust them as you don't need to mess with the valve lash when replacing the injectors.

 

After much research, I went with an SO also.

 

how do i adjust valve lash??
