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).
