I recently put gauges in my truck, and like a fool, was exited to watch the boost gauge, but quickly relized that it doesnt really move much, inless i stomp on it, i know shes only good for about 25psi but is this normal, or do i have a faulty gauge?

I am pretty sure 25 is normal. do you have a chip? i think stock they only do about 18-20. i could be wrong though!

No, all i have is an AEM brute force intake, and a 4" turbo back exhaust into 6 inch stacks. it will push 25 when its screaming tho, but other than that, it doest really produce much.

You should have some boost at pretty much any throttle position w/ a stock turbo.

It's likely that you pinched a line or introduced a leak. It's also possible that the gauge is just sticking.

im an OBS but in my 5spd i hit about 5lbs taking off and shifting around town. and doesnt really climb untill you stab the throttle or mash it. thats on a peppy street tune. smacks 15 in the face with ease when passing and pegs abou 30 and thats all she wrote. assumin gyou have 120cc injectors for a superduty? ive got stage 1s with stock nozzels and 160cc of fuel. stock it hits ~21 but takes a bit of a romp. so it sounds like your in good shape, heres a vid of my truck getting on the high way at a slightly more than half throttle stab. but tonys doesnt have much after 3/4 for throttle :doh:


sorry for the sideways vid, crap phone!! thats about 28psi non intercooled.

My early 99 stock would hit 17psi, with intake, 4" turbo back and dp in 60T will hit 26-27 pretty fast. Haven't pulled the 5er since the Adrenaline install so maybe a little more now. Fill in your sig with your mods and where did you hook up the boost line?
