How much boost does the Scooby produce if it has a PPP? on a MY99.

 

16-16.5 PSI held. Peak anywhere between that and 17.5.

Boost gauges are inaccurate.

If you get a small peak though you know it is holding the right boost. If there is no peak there may be more to come.

 

Tell me about boost gauges

I had over boost today, read just over 1.0 peek on my defi

Yet another cold morning it's fine up to peek 1.25

 

Ive de-catted my 99ppp and recently had the boost checked by the main dealer on his select monitor. came back and reported 15.8 peak. Service manager said that was high for a ppp'd car. said that they normally found 14.5 as a peak

 

They are talking rubbish. Standard car with decat can run 14 held 15 peak.

Also the select monitor reads in mmHg (760 being atmospheric) so they could have messed up their conversion.

Some dealers seem to not know what they are doing with PPPs.

Had my boost gauge checked out at Power Engineering and it was spot on. On the rollers, it peaks at around 17psi and holds 16psi. On the open road, on a cold day, it will peak at 18.5psi and hold 17-17.5psi. I'm running Optimax, MY00 PPP.
