is the boost and hp/tq gauges still accuate? i wasnt sure if i would have to get a different boost gauge

 

of course it is, but eventually the stock sensor tops out.

 

The HP/TQ is just a calculated figure, its never going to be totally accurate, but it should be close. It would be more useful to compare before/after mods with it, than to use it like dyno numbers.

 

anyone know what psi our boost gauge starts to become inacurate or limits at?

 

22.35 if its a 2.5 bar map like i believe it is.

 

thanks thats the psi limit i was looking for. once the sensor is upgraded the gauge will read correctly?

 

I would think so there has been no mention of excluding RPD (UAF) cars in all the stage kit discussions

but as said before, the power figures it displays are calculated, and are not 100% acurate.

 

2.5 Bar = 36.3psi

1bar = 14.5psi

Did you mean 1.5bar? (= 21.8psi)

 

the bar rating of the sensors is thier range. at idle you are producing vacuum, which needs to be read

 

Its absolute pressure. 1.5bar, plus the 1 bar of atmospheric pressure.

So 2.5 bar reads around 22psi on a guage, its 36 absolute.

 

Well, that's difficult to say.

RPD is for 09+ only.
SS/TC stage kit is for 08 only (as of now)

09 has a different ECM than the 08.

08 needs to be retuned to be able to recognize the 23+psi and know what to do with it.


The question is, does the 09 already have the newest tables programmed in its new ECM?

 

I keep forgetting absolute...duh

Thanks for clearing that up

 

The guage is read off of the T-map sensor in the charge pipe. I believe the t-map is 3 bar.
It would have to be, I have seen 29psi on the guage. If the map sensor was only 2.5 bar like our GXP, it would'nt read higher than 23 psi (like the gxp).
