Best wastegate controller?

I have a 2002 Excursion with 4" Magnaflow Exh & DIY intake. I was thinking about the Banks Big head wastegate actuator, but just read about the Turbo Master Wastegate controller. I like the write up. Does anyone have experience with the Turbo Master unit?

i heard that you can make my 7.3 L 2001 excursions waste gate better by just the turn or the rod that controls the waste gate, is that true and if so how would you go about doing that and making sure that you dont burn up your turbo?

Out of curiosity, I pulled the hose off the wastegate actuator. I have more boost (about 3 psi) during all light throttle driving. Max boost now goes to 23psi and holds steady. With wastegate actuator hooked up, I would see 18psi for a moment before settling in at 15psi. Thanks for the feedback.

The wastegate is there to limit boost. Basically, a smaller turbo is used so it spools quicker. The wastegate limits the max boost. I do not believe you can burn up your turbo with increased boost as long as exh temps are OK.

I have read that the stock wastegate actuator is bleeding off boost well before max pressure, so the turbo is a bit lazy compared to a wastegate actuator that holds the wastegate shut until max pressure is reached. My '87 Buick GN and '89Pontiac Turbo Trans Am did the same thing until I installed a better actuator. The better actuators in those cars made the boost come in quicker.

^Was the boost come-on noticeably quicker? I might be intersted in upgrading my wg, or at least cranking it a bit if its worthwhile

The whole idea behind increasing the air flow to the engine is to then add fuel via a chip and/or bigger injectors. Now that I have increased the air flow, I am ordering a TW 6 position chip. Just remember that at or near 24 psi our generation 7.3 engines set a trouble code and limit fuel. See write up on 4.7 volt zener diode that is used as a easy boost fooler. What chip are you using?

These turbos on these 7.3's aren't much good past 27ish psi anyways. But I guess that extra 3psi would help

I dont have a chip yet, but I'm working on a TW 4pos.
