Boost Reading Incosistencies

[Fujiwara]

I had my boost controller tuned about 6 mths ago.

On the dyno graph it shows it holding steady at 12psi.

However, on the Blitz meter, when i give it alot, it peaks to 12.7

Does this mean i'm running 12.7psi of boost or is it because they are not calibrated to read the same?

I don't really want to be boosting my stock turbo over 12, so i have turned it down to 10.x for the time being.

Assuming you can use your EBC (you mention Blitz meter, but not what type of EBC) to read boost, was it always reading 12.7 on the meter... or has it changed in the last 6 months?

Dyno operators like to "T" a boost feed for the dyno sensor from the FPR vacuum feed. Your EBC is most likely T'd somewhere else.

I wouldnt worry about it. If you wanna change it back to 12.0, then play with your EBC, easy.

It will be more to do with the two locations.

Where is the boost controller feeding from?

If its 'before cooler', then you are having a .7psi drop from the cooler is its 12psi after it.

Have no idea how to check.

ANy hints on how to do this?

Fine the boost controller, find out where its getting its reading.

I'd say somewhere near the turbo (before cooler)

Dyno is T'd off the rail (after cooler)
