Hi all,
On my way home from France in the Scoob today I had a bit of a weird experience.
Car has been absolutely fine all week covering 800 + miles, stopped just after Calais today so that brother in law could fill up. When we left station, I joined the motorway and boost was 8psi?? it stayed that way for about 70 miles, then all of a sudden started boosting properly at its setting of 17psi?
There were no vacuum pipes leaking, no engine lights, no smoke etc.
Ive never had an issue before like this.

Car has a Zero performance ecu and was recently checked at Surrey rolling road producing 323bhp. I was told by Simon from JGM that the fuelling was not quite as he would like, but not to much of an issue.

Just wondering if anyone could share any light on this.
I only ever put in optimax, or the highest grade I can find while in france which was advertised as 98ron at Shell.
