I would think that one of those has to be aftermarket. It would be neat to see the horsepower and the boost at the same time though.

 

My Aeroforce gauge will do that. On on top and the other below.

 

Both of them are stock GM parts.

 

How accurate are the boost guages?

 

I have the analog GM boost gauge AND the Aeroforce, and they both read the same boost.

 

The Digital is easier to read on a glance and you can program the lights to come on the gauge when you hit the PSI you set it for.

My lights come on at 20 and then I can glance over and watch to see what I hit.

 

Agreed the Aeroforces are a great toy.... err tool to use. Right now I have mine set to display short + long term fuel trims on one gauge, and boost + AFR in the other. Of course I have the factory boost gauge in the A pillar too.

 

I paid 23,500$ out the door (tax title license ect) for my '09 last april. Love the car and will def. be keeping it for at least 10years, but think it will be longer then that. It will be paid off in Oct. and the original plan was to get a '10 Camaro SS, but think I am gonna wait and get the turbo upgrade and a Ducati for cheaper. But I do want the Camaro in the new green
