You're problem seems to be all over the place. First things first low power with no fault codes does have to be run on a dyno, the cost...... i have no clue what is normal. Secondly the transfer pump has no direct effect on low power. The transfer pump will only cause low power because while cranking the engine if the transfer pump is weak or not working at all it puts an extra strain on the injection pump because you are trying to pull fuel from the fuel tank with no transfer pump(im guessing you have a vp44 or a bosch inline injection pump) and after time this will cause the injection pump to go bad. Third if the transfer pump was the culprit then just changing the transfer pump will not solve the problem you will need a transfer pump and an injection pump. You should be able to tell if the transfer pump is working put the key in the ignition and turn the key but do no start the engine you should hear some clicking and you should be able to hear the transfer pump cycle which will be heard by somewhat of a buzzing sound it will last for 30 seconds then stop. If you do not hear anything try turning the key off wait 30 seconds then turn the key again but this time you will "bump" the engine. Bumping the engine is when you turn the key to the cranking position but not holding just turn the key and release. If you still do not hear the transfer pump buzzing then it is not working. This will not rule out the transfer pump, it could still be buzzing but not supplying enough fuel to the injection pump which is no good either. This is when testing comes in but no dyno will be needed you need to hook up a drain line to the outlet side of the pump and do a volume test. once the transfer pump has been diagnost as faulty or not faulty then the injection pump needs to be tested and this will need to be dyno tested. the technician will need to run the truck on the dyno and hook up to the injection pump with a psi gauge to check fuel pressure that the injection pump is putting to the injectors. this is where they will find if the injection pump is bad or not on a side note the injection pump is rather pricey. if both pumps are checking good then more troubleshooting will be required.

A dyno test is usually preferable to reliance strictly on the engine computer. The dyno allows the mechanics to duplicate road situations, see what happens as road speeds and transmissions gears change, and gives them a more detailed look at what the vehicle is doing when a problem does occur. As they discovered, the problem with your fuel pressure was progressive, and got worse as the driving simulation continued. The dyno test would have been a bargain if it showed something a lot less invasive was the cause.
Personally, I would encourage a shop that has access to a dyno to use it.

What is your idle set at in neutral/park? If it is automatic it is supposed to be set at 850 rpm. I have a 1996 and a 1997 both with auto trans. and have had this problem happen after years of use. I found the idle to be dropping due to wear on the idle screw stop on the injection pump. Adjust the idle at that screw to make up for the wear spot.

Irratic ticking from the fuel lift pump

I have a 1997 with the 12valve and have an irratic ticking coming from the fuel lift pump area when I put a stethoscope on it. Could it be the primer pump or is that an electric pump next to the primer pump on the side of the engine? Curious if anyone has come across this before. It isnt all the time and is mainly when the engine is at operating temp.

Looking down on top of the engine it is at the back of the injection pump and you will see the thottle lever resting on the top of the acorn style bolt head. It is easy to see if you operate the throttle by hand and watch that area at the back of the injection pump. This solved same problem on my 97. If it is automatic set it at 850rpm, good luck
