stock wastegate help?
does anyone know how to adjust the wastegate? i've read that there is a nut you turn to mess with the psi? i'm a 2.2 with the k04 and i spike 15-20 pounds wayyyy to much and annoying. i want it at about 10 psi.

lol you can't put a bc on and lower the boost past what the wg spring is rated for.
if there's no adjustment you can always pull the iwg and weld it shut, and get an ewg.

In your case a mbc is totally fine to use with the k04. I wouldn't honestly mess with the wastegate adjustments really unless you know what you're doing though.

Well, you can try tightening up/extending the wastegate rod but you may have to get an external wastegate and just plug off the stock turbo wastegate. A boost controller can only adjust down to the wastegate boost itself. Unless you can find a lower boost wg actuator off another turbo to retrofit.

Extend the wastegate by loosening both nuts and cranking the one closest to the wastegate actuator(where the vac line is hooked up) towards the front of the car if you're on top of the engine bay or towards the back of the car if you're under the engine bay. Then crank the nut furthest away from the wastegate the same way until you start feeling resistance. Then tighten the one closest to the wastegate actuator towards the back of the car if you're above the engine bay
or towards the front of the car if you're under the engine bay until its nice and snug on the rod.

You may have to loosen the one closest to the actuator more as you try to get resistance off of the one farthest away or you could bottom out on the nut closest to the actuator and you don't want to do that until you feel resistance. Not caused by the nut closest to actuator but the wastegate itself.

put a vacum hose on the nipple on the wastegate, then run it to ur manifold, or anyplace u would usually hook up a boost gauge to read boost, and the turbo will only boost as high as the spring in the wastegate is set to. that should be safe till u get ur boost controler
