Default gm bcs with an xpt stage 2 worth it??

i dont understand the point of the gm bcs if the xpt stage 2 already raises the boost to almost 17 psi. what else will it do? i have an 04 xpt stage 2 wrx and im dying to do something more to make it go a little faster.. but i dont know what i could do without spending more than 300 dollars.

well can someone school me on that gm bcs? please and thank you.

btw does anyone know where i can find a more aggressive stage 2 map??

The point of a GM BCS is to control boost better than the stock unit...basically an upgraded BCS. It won't necessarily make you faster, but will make boost levels a bit smoother and consistent.

As far as a more aggressive stage II map, you're best off getting protuned, as the XPT maps are already fairly aggressive.

The GM BCS map is an offering for users who cannot achieve target boost without the help of wastegate arm adjustment or running the stock boost solenoid at 90% or higher. It allows more headroom and greater control of the turbo, as well as offering an upgrade path for future mods. I think the GM BCS is one of the best bangs for the buck that you can do, especially when you plan on replacing the turbo or going for higher boost with Meth.

I don't think you can get any power, maybe a few hp IF you cannot hit target boost with the stock solenoid

Like I said, it will allow you more opportunity to make power. The next RACE map for 02-05 WRX will only require an Injen CAI, STi TMIC and the GM BCS in addition to current mods. We run it at around 20psi. Right off the bat you may not make more power just by adding it, but you will shift the powerband slightly lower and retain it slightly longer.

That is Stage 2.5 for the 02-05 WRX. I have created a map for everything but the turbo/injectors, so you basically have a transitional period with the benefits of all of the parts prior to the turbo swap.

Any idea when the RACE map will be available? I see you have one already for the 06 WRX. I already have XPT Stage 2, but I'm not ready to replace the turbo yet, and I'm looking for a little more power. Will I be able to run 92 octane on this map? It's the best I can get without going to race gas.

Well, you're asking him to make it to that HP...every car is different, so are the dynos, so he can make a map, sure, but doesn't mean it'll be 320hp, maybe more or less.

Why don't you just go get a custom tune

I don't know any tuners that do ecu flashes. They all tune ap or utec and I don't see why I should spend 695 for ap or 1000 for utec and then go get protuned for another 500 bucks. Thats a waste of money to me I was just hoping he would make a map that would be 300+.

You can not run the GM without a tune specifically made for it. It's a bleed (stock) vs an intercept (GM) boost control system.

Thats the thing everyone in Maryland wants a cobb ap to tune or turbo xs to tune. I dont know anyone around to tune with enginuity or anything like that. So I was just hoping an ots map would come out making like 300+ and I wouldn't have to drive across the east cost trying to find a tuner. Thanks for the feed back

You can contact 06rexwagon, 555motorsports, get a dom tune dot com, and a few others.
Just to name a few

A lot of people get spike issues with free flowing exhaust and the stock bcs. I was one of them. No matter how much I adjust my wgdc map I could not stop spiking 23psi. I bought a gm bcs new for 40 shipped and its a world of difference. Much smoother as mentioned above and I can hold more boost up top with this over the stock unit.

The XPT maps are great. They are pretty aggressive but have room for improvement for those that like to tinker with their car. Im running a XPT stg2 w/gm bcs and LC. Ive modified it quite a bit but it was a terrific starting point for $50!!!
