I need instructions on how to adjust the fuel plate forward for an increase in power. How much of a power increase can I expect to gain from doing this? Can anyone direct me toward detailed instructions for this procedure?

 

Hi Adam,

Since you're in the 1st Gen Forum I'll assume you have an '89-'93 model year truck...

If that is the case, you don't have a fuel plate like the newer trucks...
You would be adjusting the "full fuel screw" to up you fueling/hp/smoke/heat.
If you are an auto tranny, then you will have some limitations based on the tranny/tc's ability to deal with the increase.
Basically a stock truck should have instruments to start out with. It gives you a baseline on which to judge ALL future changes and modifications.
Ok, how much HP??? Well, you can quite easily get 50-60 rear wheel HP from just a bit of pump tuning.... that's REAR WHEEL, not flywheel.
Can I suggest you do some digging and reading as well as picture hunting.
There are some good "how to's " in here and other sites. Also some good pics to give you an overview of the various adjustments....
Here is one pic to get you started and I'll post a couple more in the following posts below.

Thanks, Bushy. This helps me a great deal. I'm driving a 92 5 speed. It has about 310,000 miles on it now but it runs really good and I've never done anything to it.
