yer, as per subject. the included oring OR the stock 3bar oring (on the 4bar) leak like a *****..

good job...

i had been meaning to do mine for a long time, but when i was seeing a 5 psi difference on the dyno tonight i knew it was time

I guess on the evox platform its SUPER bad, because lowest boost reading = less fuel AND boost correction tries to add boost..

so your tune that is 25psi and 11.5:afr is now 30psi AND 13:1 afr..

**** yeh!
