The big bonus for installing an adjustable w/g actuator is for the adjustability. There are better adjustable w/g actuators on the market than the big head. If you have another way to control your boost then I wouldn't think you would need one.
Turbomaster wastegate rod is easy to ajust, you want more boost, tighten a 10mm bolt... Need to back it off a bit, then loosen the 10mm bolt... I think dieselsite sells them but I would post up on the vendor section...
The stock acutator has like a one lb. spring in it so the drive pressure is more likely to blow it open makeing it hard to control boost. The BH has a 20 lb. spring as I recall so the drive pressure can't blow it open. If you just unplug your waste gate you drive pressure will go up, your boost will go up, and your intake temps will go up. At a certin point the turbo will be making more heat than is beneficial and though it is making more boost will be flowing less air and you can loose power. boost does NOT = power. I've seen more than once when someone hooked their waste gate back up and made more power and all of a sudden started getting better mileage. A properly working system set to the right boost level will be the most efficient and make the most power.
I installed the Banks BHA on my truck and worked pretty good. I am seeing higher boost pressures and I can feel a power difference because of it. I thought it was worth the money, but I bought a used one. I know dieselsite.com sells an adjustable one.
