So after a low dyno graph, Ive changed out the bpv and put alta boots on my 03 with JCW 210 kit.

At idle its at -8.4, Ive read posts that say -7 is normal. I have not set it as I do not understand how to adjust the atmospheric pressures with my location, San diego

I wish I had the scan gauge II before dyno and swapping parts but regardless ive only seen 13.7lb of boost.

Is this on par with ever one else?

 

i get over 17 psi, according to my gauge.... but I have a 17% pulley. sorry, no idea what it was before the pulley...

whats your "210 kit"?

 

17% pulley on an '05 JCW R52, Torque OBDII app shows max of 15.9 PSI ... :(

 

your idle vacuum seems low to me.

i've got the jcw200 package along with a rmw cam and my idle is at -15 vacuum. max boost i've seen was 15psi under ideal weather conditions. normally it' around 12 with the muggy oklahoma weather.

your 13.7 sounds accurate for the pulley on these

 

Ive started seeing how big weather conditions play a factor in readings.

I saw 15.6 in 5th gear few weeks ago when I was touring with another mini.
