External Wastegate - Stock BCS setup
I was just afraid to risk burning out the driver on my ECU with incorrect intall of this Solenoid... (mistakes can happen with stuff like this)
.
NO NO NO!
That thing is a POFS!
IMO I view it this way;
You either want the simplicity of being able to crank a knob and dial in your boost almost mindlessly easy.
or~
You go with the stock ecu controlled boost with a GM 3 port solenoid and allow for some more flexibility but also some more seat time getting it dialed in.
The profec B should be your last option just short of shoving your spleen into the engine bay to control boost. Mainly because they are crap. And the additional cost of the controller (when the same can be done for the cost of the GM solenoid on the stock ecu) is completely unwarranted.
I prefer a cranky knob - *done* (mbc) mainly because there are other aspects of the car I would prefer to spend my limited time paying more attention to tuning.
But folks such as razorlab have got the EBC / stock ecu thing down to a science.
So if you want to go the EBC route... do whatever he says.
Trust me.

Trust me.
also, once you have the thing installed, turning up the boost is done by turning a knob as well
greddy profec B is pretty dang easy to use.
Doesnt have to be 40psi capable - I want to run max 25psi.
Hi & Low Boost - dialed from inside the car, simpler - better - faster!
If it can do that without any issues, then its a POS that meets all my requirements.

welllllll external EBC is "probably" better at dialing in boost, that said I couldn't get the HKS EVC to run properly, and have found GM3port + ECU boost good enough.
however you may want to run ECU boost so you can take advantage of mapswitching... running an external EBC means you need to change 2 things to switch maps instead of only 1 thing...

Thanks Tephra, thats an important bit of information...
I am gona order the GM 3port.
(Was just paranoid about stuffing up my ECU, but you guys have put my mind at a bit of ease on that one...)
ps. I found that with a T piece in the vacuum hose between the Wastegate diaphram and the BCS it does allow limited control of boost...
