I've had mine trip too phil, quite unpleasant. Often after a long WOT in third, if you back off a little the boost gauge snaps up to 20psi (or more), maybe the DVs can't bypass that much air mass??

Mine only goes to 17 on some days / conditions though.
Thanks mate,

I was just going to ask this as I am looking at the JB4 interface now.

Will change it to 18 when I leave work tonight. Mine has never hit 17 then as I suspected. For me, it could be simply because I rarely run back to back tanks of premium fuel and have only recently fit the upgraded parts.

I'll fill up with V-Power later and let you guys know how I get on, after making the change.

Thanks
Matt
