trust the mech. boost gauge or quad/map sensor? - Pirate4x4.Com : 4x4 and Off-Road Forum

D-LUX · 06-29-2012, 08:59 PM

just like the title reads...I'm installing a boost elbow this weekend and would like to know which to trust

isspro boost gauge will read 20 ish psi under WOT and the quad will usually read about 28 to 30...

i know the gauge reads correct been tested with shop air and im pretty sure it doesnt leak where im drawing pressure.. its hooked up using a boost bolt that runs into the intake plate.

any advice or thoughts?

fueling on truck is just a quad adr w/ stock injecors

Mechanical is the accurate one. This is taking the reading straight from the horse's mouth....

are they on the same place? you will always get a higher reading just after the turbo, and a lower in the intake manifold

alright found and fixed the issue.. it was the quadzilla, more specifically their board has an issue so its getting sent back today...

going to sell it when its fixed looking to stay away from fueling boxes as they seem to really put a hurtin on these vp pumps, going with a set of 150's from cpp and just a timing box like the ts mvp. should be a clean burning 340 to 350 hp. perfect for towing
