Anyone know what max boost is running stock ECU settings , which I assume is the 7.8 version ....is it higher than a non x50 car or the same. Car is 03MY.

Stock boost is .7 on a non x50 and 1.0 on stock X50

jimq

the most mine gets is .9 and usually .8

Stock X50 is .8 to .9 bar max under WOT 3rd gear and 4th gear..

Fastboy

I've seen .9 on mine at the track

Before I added a UMW flash, it was consistently 0.8 to 0.9. Higher in cooler weather.

Spikes you can get, but the number you want it what is holding more or less constantly at peak boost.


Now I see 1.2 to 1.3, depending on ambient temps

Pure stock 2002........generally .8-.9. May get an occasional 1.0 under heavy load at the track

Stock 2005 Turbo S (x50 std). 1.1 bar.

Not sctock. ;-).

I have X50. Std was 0.8 - 0.9 (spike) as 2 posters already said. Now I have flash and I see 1.2 to 1.3 (spike) on a cold day.

Thank you everyone for the input. Car back at dealer to see why it is not boosting up all the way

I have a non x50 2003 that gets 0.8 which I verified today on track. Mile long back stretch at VIR running through the gears with an ambient temp in the high 50s.
