Personally watched a 2008 black cobalt ss tc with a 3in downpipe and intake and manual boost controller.. (mock up like any other manual boost controller) run a stock 6.0 gto.. I have one laying around but how safe is that. I feel as If it is sketchy..

 

don't touch boost without tuning. Will cause all kinds of problems. You can't just crank up boost without tuning. And if you're gonna be tuning, then your tuning software can control boost levels. So it's unnecessary on these cars.

 

That's exactly what I was thinking! No tune no messing with boost unless a performance part adds psi.. Corret?!

 

Then your not adding boost the part is.

 

usually adding bolt ons will actually cause a psi drop due to better air flow. Boost is a measure of restriction. You don't wanna touch boost without adjusting for afr, timing, etc. Even on a car that requires a manual boost controller like my car you still need to tune for boost changes.

 

Makes complete sense lol. I knew I would ask edited strapping on a boost controller. Prolly won't even do it after I get a tune

 

no there's no need for it since these cars can control boost through the ecu. It's really just gonna be more clutter in the engine bay.

 

Thank you!

 

What are your goals for the car?

 

Eleventy billion HP.

 

First thing first
I have the Kn SRI
and a ZZP catless DP
Next will be a tune from them and have them install the gms1 (I THINK)
Is the GMS1 worth the extra 130 bones??

Then I would like to powder coat my rims black and do the EVO mod and throw some retros up front.

Then the forged BPV and catback exhaust.
After that just store it for the winter and hope to do zzp's polished lnf head/cam/combo kit...

Will see tho. The tune and visuals will be in the next month.

 

It's actually less clutter.


Seriously though, as Tommy said it is pointless on your car/setup.

 

Thanks for the help guys.. Just waiting for tommy to answer my next question.. hehe

 

Oh, well I stand corrected
About gms1? It's only worth it if you want to keep your warranty. Otherwise an aftermarket tune will be cheaper and more effective.

 

Mbc is annoying when you want to change boost levels.

 

I find it easier than flashing a car that is controlled by the ECM. It takes me like 7 seconds to change the boost on the car. Even easier would be a electronic boost controller that you could adjust from the driver seat.

 

True. I heard all the current ebc's on the market suck tho. Im thinking about having my mbc mounted inside so I can do it easy. The trunk popper area is a perfect location.

 

You could do like me and mount your mbc in the car, lol...I found a boot in the firewall I was able to get around. You just need more vac line.

 

lol, lazy. I could but i really like my mount position for the controller under the hood. Plus it is pretty clean and i even wrapped the lines with that corrugated tubing so it looks like the wiring in the car. Possibly it protects the lines from heat as well, a lil?

Really the only thing i can't move is the oil feed line... that sucker is sitting on the edge of the manifold and i cant find a way to get it not to touch. Thinking either a longer line or some header wrap for it lmao.

 

So does should I spend the extra 130 bucks towards the GMS1 when zzp tunes my car?...

 

The GMS1 you are referring to is the sensors....ZZP is tuning the car.

And yes, I would get the sensors. They are more accurate at higher boost levels.

 

part throttle, full boost.

ECU tuning is the way to go (for stock-like turbo setups).

 

There is this. Honestly it is the biggest issue with pedaling my car down the 1/4 mile on street tires as well. Lag, spin, lag, spin.... It would probably murder a stock clutch as well with the way it would make torque.

 

You have to relocate it. Move it to the far right oil plug in the block. Remove that plug and place it where the stock oil feed was located. You can get a rubber wrapped metal clamp if your kit didn't come with one and mount it to one of the water pump bolts.

 

And don't forget to coat the plug with grey rtv just as you did the oil feed fitting.
