how much can std fueling take 10psi?

also whats the most boost you can run on normal fuel ie leaded 95 ron as apose to optimax or super unleaded?

I ask cos its anoying have to drive 5 miles to get some when normal garage is just round the corner, thinking of turning boost down as its running 14psi with no history and i cant afford a set up for a few weeks.

chears Paul.

 

i would have thought it depends on the exact spec of your engine...

i know what you mean, i think the same thing about my car...

buying optimax is a pain cos the nearest place is about 7 miles away
