so it doesnt sound like the wastegate opens till about 5-6k (no tach), ( i have my wastegate hooked up side port on tial-mbc-hotpipe and the top one is open) and the car is way to slow for 3071 at 6psi. the fire ring thing is in
but, it builds 6psi way earlier and holds it to high rpm
the idle is super up and down, but the up parts are still low and it almost stalls. i sprayed starter fluid everywhere and the idle didnt raise so im not sure if its a vacuum leak. but my vaccuum at idle is 16ish when i first start then a few secs later fluxuates between 10-15 depending on what part of its bumpyness its on.
i can kinda hear a fshhhh sound when its boosting, but i am not getting a serious cut out like you do when you boost with a vacuum leak ( i have no cut out whatsoever)
also it smells like the car is running real rich
its not an individual cylinder because when i unplug injector or spark plug in a cylinder it gets worse.
tommys dad redid cam timing no help.
my setup is s15 injectors (reddish/brown), rb20 maf, jim wolf ecu.
any help would be really appreciated

idle sucks and it feels like boost isnt hitting but my guage reads 6psi cliff notes but i think you need all the info

With that qoute.

I'd say check for boost leaks.

What does your boost gauge idle at when the car is on and in neutral?

it fluxates, 10-15, but i checked and sprayed starter fluid seriously everywhere, and my car doesnt cut out like when you hit boost with a vaccuum leak

Check your couplers, clamps, IC piping, also you should try to comp. test it. Did you spray around all vac. lines. Charcoal can, tb, intake mani. Just some suggestions. GL.

Boost leak then.

10-15 vacuum during idle is bad. (should be around 18-22psi)

Your leaking air somewhere.

Maybe a line where your not shooting carb cleaner at.

Try doing a boost leak test.
