2010 HHR SS Turbo Upgrade, auto, RPD
 

The title of the post is a mouthful eh? :smile: Has anyone else with the upgrade and the RPD noticed that the "Boost" gauge is inaccurate? If so, is there a fix available? I haven't found an update on TIS2WEB.

I can see this issue contributing to the "I have the upgrade but my car doesn't hit 20 psi" posts. There is a discrepancy between what the Tech2 is reading and what is being displayed on the PRD, it can be as high as 5psi at times.

Thats Interesting haven't considered that the gauge could be wrong might have to get one of those aero force gizmos !:twothumbs:

So at least I'm not the only one with this problem. My RPD boost gauge (Stage 1) never goes over about 17-18 lbs of boost tops. I've had it to the dealer and checked everything myself, and the stage 1 is installed properly.

If you can, do me a favor and check your HP gauge and see if it goes over 260, because mine refuses to.

maybe its the blue color?

Makes sense to me.:twothumbs:

when I get my intercooler and hotside done I'm going to have Vince tune it I'll let you know how it works out at this point mine will go a little over 20 but wont stay up there.So I'm sure the stg-1 is working it's just not consistant at all is your 5sp or auto?

Yeah I've been thinking my boost gauge is off 2 psi because everytime I tell Vince I want a 24 psi tune and then check the tune on my boost gauge its always 26 psi.
It was that way with the K04 and is that way with the new BNR GT2871.
To much of a coincedence imo that two different tunes, for two different turbos both are off 2 psi in the end.
I'd like to get a aeroforce gauge also, I've been waiting all winter to see if that guy was going to make anymore single column gauge pods again for the HHR's, so far its been a :thumbsdow.

would that put them both on the A pillar if so I want one too
if you put them over the wheel can you still see your DIC ??That one will get me in the so I'm childish thread :clueless:

That's a big NO sir. Check my gallery as that's where I have my Aeroforce gauges set up. The DIC is blocked somewhat but 95% of what it reads, you can monitor on the Aeroforces so it's a moot point. I may change the placement later on if I feel up to it but I'm used to them now.

Later
