I had no brakes at low rpm , tried the canister , eventually had to install electric one from comp cams .I installed it in the fender , had to cut a little to fit , do not let it touch the guard as it will do damage.

what size camshaft were/ are you running?

dont personally know the specs but it is big , takes most of my vacuum that when i apply brakes the pedal hits the metal. once i installed the electric pump the brakes work fine .

238/242 .600/.610 on a 112 lsa. tuned to idle right at 1000 rpm

my brakes work pretty good but took some getting use to, a quick pump of the peddle helps under hard braking.

What is funny to me.....I have had three GTO's now. All three with heads/cam.
Two were fine and the third had the same problems you are mentioning.

Sounds like maybe the issue is with the brake system rather than the lack of vacuum? I never could get it to work right at low speed. Demodded and traded it last year for a G8.

Good luck getting it worked out.
