How much Boost?

I'm trying to figure out how much boost my truck runs, I have a 2000 f-350 superchip, striaght exhaust, filter. I'm think around 30psi but not sure. I want to get a boost gauge, and autometer has a 30psi, and a blower 60psi, but the 60psi comes in 2-5/8 and I need 2-1/16, or do I need to look around more?

Thanks Derek

I'm take it this is a diesel, right? I took my father's 05 F-350 6.0 PSD to the track and it never made another above 30psi.

I looked around more and found a 35psi gauge, will this be good?

Thanks Derek
If that is all the upgrades you have, then you will not see over 25 psi due to de-fueling. You will need an over-boost eliminator or relief valve as some call it, to see more boost. My gauge goes to 35 psi and with my mods, I can only hit 32 to 33 psi. I have Auto meter Z series.

Yea - what Fordafied said... ALSO note that the stock turbo likes to be kept below 25psi boost. Going over 25 will shorten the life of the turbo, and you are out of the efficiency range of the turbo too!

if you are repeatedly going to be over 25 psi, i would recommend a ball bearing turbo. it has a bearing instead of a thrust washer, it eliminates all possibility of a blade touching the housing at high boost pressures. it is more efficient than stock at those high levels too. also quicker spool up.
