hey can any one tell me how to crank up injector pump on 84 gmc with 6.2. just want to get little more out of it. 20-25 horse.

 

There's a cover on the side of the injection pump, remove it, then turn the screw about a half a turn or until you achieve the amount of power you want.

 

thanks. turn it im assuming? is there any thing that can be done to improve air flow on that motor?

There isn't much you can do to improve airflow, other than adding a turbo charger.

 

supercharger

 

is it necessary to get an egt gauge if i turn up the ip on a 1987 6.2 c code 1/4 turn?

 

it would be reccomended. dont want you to hurt your engine

 

I tried to turn up the pump on my truck last night and I didnt have enough clearance to get the srews out on the side of the pump. Does anybody have any tricks to doing that or is it necessary to remove the intake manifold. (I have an egr intake)

 

yup probably going to have to take it off

 

you can take the top off the pump and access the screw also.you will have to take allen bolt out from rear of pump to remove gov assembly out of way just make sure to install as you took it apart
