Help! Car stuck at 5psi, and its slow! plz read

[ulti]

So i just picked up my sr powered 240 on friday, when i bought the car it wasnt boosting properly but it runs great, just pulls like an N.A. car. Anyways i hooked my boost gauge when i got home to see whats going on, i do hit and hold 5 psi but the car feels gutless. i checked timing and set it to 15*.i dont know much about the car yet. it has stock sidemount IC with the recirc valve bypassed. Im new to SR20's but not turbos, please help me diagnose this I want my racecar!!!

Maybe a stuck wastegate

Maybe a stuck wastegate

Good thought but its not likely considering a wg stuck open = no boost. And a wg stuck closed = tons of boost

it could be stuck half open. half open = 5#. but maybe crack, hole, or loose fitting on piping/intercooler causing pressure leak?

Did you actually check and reset your timing? I had a similar problem recently, my timing was off after I took my head off because I must have bumped the CAS when I installed it, set it right again and it is fine. If you have a vacuum gauge check to see if you get around 19 or 20in hg vacuum while at idle.

Check all your fittings on your intercooler and all vacuum hoses you have hooked up.

i put on a fmic and all new piping, but after about a day of driving... think my maf took a crap. its at the shop rite now, they are diagnosing it as we speak
