Really confused with need for Wastegate actuator

Hey guys hoping you can clear some stuff up for me.... I have read about 20 threads today trying to decide if i should purchase dieselsites wastegate actuator for my stock 38 when i purchase my WWII.

Currently im running with the red tube unplugged and seeing 32psi max on the setup. i have read the description of the actuator and im still unclear if i will see any benefits from it or not. I wont be upgrading turbo and injectors for a year or two as i have just finished MOST of my supporting mods. I dont want to waste money i can save for injectors and turbo down the road, but that is definitely a ways down the road.

currently im running (performance wise)
BTS trans
Dual fuel pumps (one will feed each head, regulated return, not yet installed but in the mail)
6637
DP tuner
4" downpipe to 5" exhaust, no muffler
Bellowed up pipes
gauges
203 deg thermostat (being ordered with WWII)

if i will see an mpg or performance increase in daily driving or when i want to play and go fast it will be worth it to me.

im just unclear if unplugging the red tube does the same as the actuator (with the exception that i cant control exactly when the wastegate opens)

seems to be many mixed reviews, and the only guys ive seen reporting gains did not have tuners, or many upgrades in general

So unplugging the red tube is just as effective ?

Stock sticks, stock turbo, adjust the actuator arm by shortening it till it takes about 26-27 psi of air pressure to open the gate once the arm is back on.

Any detailed write ups on how to do this?

Re: Really confused with need for Wastegate actuator

Its pretty simple. Iirc, all you do is remove the e clip holding the actuator arm to the exhaust housing, and turn the rod, re install it, then put compressed air, regulated to whatever pressure you want, to the actuators nipple, where your red line used to be, it'll probably take a couple tries to get it right.

Re: Really confused with need for Wastegate actuator

Definayely need a waste gate controller of some sort if you are getting a new wheel so u don't over boost stuff...factory or aftermarket. Whichever

Re: Really confused with need for Wastegate actuator

From all the forums and arguments about it it sounds like the factory waste gate starts dumping air at 5 psi no matter what you do, is this correct or not?

Wrong. The preload on the wastegate from the factory on some trucks would blow open at 5-7 psi, but once you adjust it to where you want it, it wi hold fine. I adjusted mine to 26psi of preload and it would make 32-33psi without any problems. My exhaust back pressures was never more than 40 or so psi peak. That was running a WW2 which helps balance the back pressure to boost ratio.
