tonight i went to pepboys to swap my broken autometer out with a new one and sure enough the new one works and not the old one that was supposed to be so good. my question is do you know why im only seeing 6 psi instantly at night on the 2.6" pulley with NO alky injection and also what should my vac read? im seeing 14 at idle right now. thanks.
mine reads -22, and with my last engine -20, altitude can have an effect on this too though, I am at 790'

i see my vac at 20 when at idle. and 5psi on the stock pulley
I see 17 - 18 when cold and 20 when warm...

i just turned up my idle so it idles at IDLE at 1300 and now im seeing -20 so im fine now, boost is still 6 psi though
is there a bypass valve on those things? might want to check and see if it seals. Spraying carb cleaner around all of the gaskets and vacuum ports will be a good indicator of any leaks also, spray it on with the engine running and if the motor stumbles when you hit a certain spot, you've found your leak. You shouldn't have to raise you idle to see 20 in/hg, and actually, you should see less vacuum at 1300 rpm than 800, since the iac and/or tb will be open farther, making less of a blockage for the motor to pull against (which is what creates vacuum). Sounds to me like your gauge is whack, or you have a leak.
Oh yeah, is this a boost gauge with an electric sending unit? Be careful, as some of those need a constant power source because they recalibrate to atmospheric pressure when the ignition is turned on, and this can get screwed up if you have it powered by something that loses power during cranking... meaning that it could calibrate 5 in/hg as atmospheric, which could make your max boost read lower and your vacuum read higher than it should. We had the same problem on Rich (Exterminator)'s car before we realized it needed to be powered off of something like an ecu power source, which does not lose power when cranking the engine, as te radio/headlights and more accessories do.

6psi on stock pulley and -14psi at idle.
well i turned my idle up some, its not choppy at all now and at idle vac is 20 so im good now, boost is still 6 psi on 2.6 pulley though
damn coolingmist sucks, i went to put my kit together last night and noticed i dont have 3 parts that i need that should be in the box
wait what parts did they short you on... and was it there fault or do those parts just come seperatly. Im looking into getting an alky kit and i just need to know were i can get the best quality one and make sure it comes complette with everything i need.
it was there fault i called the dude and hes like ill have them shipped out to you. they claim its not some company that puts kits together outta their basement but i think thats just what it is, i mean how you gonna forget to have something in a kit if its a actual kit unless you make it up upon request. i was short on the fuse holder, fuse wire, 10amp slow burn fuse and a fitting that goes to the pump. it also didnt come with any mounting screws but thats no biggie.
do you maybe have a ported out head, larger cams, freeflow exhaust? all of these things can actually lower your overall number of psi you will see for boost but in actuallity these additions are making each psi more efficient. 6psi does seem a bit low to me. With my setup 2.5" pulley and cooling mist w/ m8 nozzle and methanol i see about 10psi, before the built "race" head i was seeing about 12-12.5psi.

i do have a built head, i have the works done to my engine. I was seeing 4.5 before rebuild and the 2.8 pulley and now with the 2.6 pulley and rebuild i see 6 instantly and it pulls twice as hard, so i guess my 6 psi is decent because the cams and headwork make up double for it? if coolingmist ever sends me my parts they screwed up and forgot to add in their kit ill see if i see anymore boost. all i know is i ran 13.901 with 35 shot and 4.5 psi so now im surely in the mid 13's easily with this 50 shot and 6 psi, but i wanna see high 13's with all charger and injection if i ever get the kit on and HPT on the car.
i thought alky injection kits helped to prevent detonation making more power with less heat. i didn't think they added more PSI tho. am i wrong?
don't mean to thread jack but i got a little confused after reading this.

ahhhhhhh, i missed that you had all that other work done... that explains why boost/vacuum are off from people with that pulley on a stock motor. PSI just shows how much resistance there is to airflow... if you remove those restrictions, you'll see less psi because more of that air is getting to the cylinder instead of backing up in the intake tract.
