It's possible that your stock gauge is inaccurate. It's also possible it could be a close representation of your actual boost? What breathing mods have you done?

As for the topic, no one else wants to chime in here?

personally i would recomend an aftermarket gauge, incase you ever blow a waistgate vac/boost reference line like i did.. I looked down and i was at about 20 psi... and stock gauge pegs at 8 so youd never know it if it ever happened to you.

and i like to adjust boost inside cab with moddified manual air regulator, but thats just how i roll... bleeder valves work pretty good too and way cheap...so will the washers just dont over do it...

wow what a diffrence i thought i would shimm this turbo while i wait for my new stuff to get here,what a blast on my way home from work, only takes about 20 minutes to do to,i only put in 3 washers but they looked alittle bigger than normal so i only put in the 3, my stock gauge would bary when i laid into it would let loose even easier thanx for the thread was lots of fun

Bullz_EyE everything is stock but the shims. Just had to try it out. What is a good aftermarket?

I think that joel williams way sounds good and safe. I will take shims out on my next day off. But its fun!!

i wouldnt go over 10 psi on stock ct-26, i killed 2 stock ct's doing that..
and i would not play with a boost valve untill you upgrade your boost gauge 4 sure.. nice piks on your other post.. gj and happy boosting.

Would I be safe doing this with 3 or 4 washers on a totally stock supra? This is just too good to resist, but I don't want to mess anything up.

Also what is the average price for a decent gauge? Im looking online and they seem pretty expensive (for me).
