gauges??

[ridinak]

so i bought some gauges and i got boost, egt, and fuel pressure and im not sure on how to or where to install the sensor for the gauge and when i hooked up the boost gauge its only reading about 7-8lbs boost and that was really gettin on the thottle im hopein its a bad gauge but what could it be other than the gauge? ive been looking into a fpr shim what do yall think about the shim

[Jarrod B]

boost on a obs im not sure besides tapping into the map line

egt is best at the lowest point on the driver exhaust manafold

fuel pressure im not sure on.

and fpr shim from what ive heard isnt much gain.

thats where i hooked up the boost gauge was to the map sensor line i got a spot on my dp for the egt sensor id just like to figure out whats up with the boost

[Jarrod B]

thats the max i saw on mine when it was on the map line. i dont know if thats normal or not.

i tapped into the map line also an mine will read maybe 15 lbs if a stay on it long enough...tapping into the map is the way to get more boost

i also read 15 psi in my 96 obs which is stock and fpr shim is a real cheap and easy upgrade i would do it just watch your fuel pressure after you do it. gave my truck a slightly better idle and little better throttle response

aight thank you for the info im kinda thinkin that i got a bad gauge then cause ive never seen it get above 8lbs when its warm and i get on it. do yall know where the best place to mount the fuel pressure sensor so i can keep an eye on my fuel pressure i was thinking some where near the fuel filter but i want to get the best and most acurate reading that i can on this gauge cause im planning on doing stage 1 injectors and fuel system.

[rcfatcat]

usually you mount the sending unit for the fuel pressure guage on the fuel pressure regulator. atleast thats what i have seen many guys do

and another thing if you put that probe in the downpipe for ur pyro it wont read accurate or protect you since it needs to be post not pre turbo

ive seen this "fpr shim" mensioned a couple other places...what is a fpr shim? an also on the fuel pressure gauge ? ive seen were its useless to have a fuel pressure gauge because the pressure pulsates so much that the gauge cant comprehend on whats goin on...BUT thats what ive read because i was goin to do the same thing but after reading that i didnt put a fuel pressure gauge in...
