What is the best way to get more power out of th 12v fuel pump? I am thinking about a BD fuel stop plate. If I do this do I need to push more air.....new wastegate? I have a K&N intake and 4" turbo back exhaust.
The best way to get power out of the 12 Valve is either through a fuel control plate or injectors. I usually recommend the fuel plate as it less money than injectors but if you are up around 200,000 Miles it is recommended to replace the injectors, so for less money than OEM replacements you can pick up a set of 40-60HP injectors.
With either option it is recommend to advance the timing about 1 degree and get more air.. intake, exhaust and possible a performance turbo. Our BD injectors come with a performance bleed orifice to prevent the wastegate from opening so a wastegate upgrade is not necessary.
Putting in a set of stock OEM injectors will wake the truck up and help with fuel economy. A set of performance injectors will not only wake the truck up but also add a good 40-60HP. With the performance injectors you may see a small increase in fuel economy but definitly will not loose any if your driving style does not change...
It usually does change for a while with more power
So to answer your question the fuel plate is not necessarily needed with the injectors but can be added in addition to the injectors for even more power. Other mods should be used with both injectors and a fuel plate installed. For example an automatic transmission will not hold 100 extra HP, the factory turbo should be replaced with a performance turbo and gauges are a must.
Not to steal any business from dave, you make that decision, but here is my .02. Just grind your stock fuel plate and slide it forward some or all the way or whereever you find you like it. Get an adjustable boost elbow to raise boost pressure. Depending on how much you grind the plate and how far you slide it will leave your clutch or auto screaming. Obviously guages are a must. Then when that fun wears off you can get injectors, turbo............

No worries about stealing business away from me that's not a concern or what this is about, everyone sells these, if not from me get it from someone else but save the troubles of doing it yourself!
I will disagree with tractorpuller... being a fuel lab as well as a diesel performance company, I know these pumps and the problems associated with moving the plate around, spend the couple hundred and save all the guess work, grinding time and black smoke puking out the tail pipe, it even comes with a bleed orifice.
I ground my own plate and slid it full forward, and it made a HUGE difference. I also adjusted the smoke out with the starwheel. I even still have a stock clutch with 181,000 miles, it is getting to the top of the pedal but seems to be still holding on. I have not had a single problem YET. I also did some grinding on the afc arm. I love the difference.
i have a home ground 0 plate full forward in my truck and its great. but i don't tow anything thats more than 2k, so i won't have to worry about egt's but i do have a pyrometer and boost gauge. and now i want a 3kgsk to give me full fuel to 3200 and shift kit to hold the extra power a little better.
if you don't think your up to this task ask anyone on this forum who lives near you and im sure they will help you out. or you can just go to tst. and order a fuel plate with the boost elbow, and a video showing you what to do for $225. those plates are made by a retired cummins engineer i think he would know how to make something that is safe/reliable.

Well there you go TBDAN, looks like the experts are telling you to get the grinder out and slide er all the way forward. If you do not have the skills or tools to do so, perhaps pull the plate and send it to one of these helpful guys and they can grind it up for you.
If you are not comfortable grinding it yourself and can not get one of the posters here to help you or you can contact me and arrange to have one shipped out to you from one of my vendors in your area.
