Hi all,
well i just got back from Wollongong, and i think (after reading some threads on here) i am experiencing over boost.
it happened twice, both times on a hill. i would put the peddle down and lose all boost, until i release the peddle and reapply, then i would get full power.
also, the boost varies as i go through the rev range. comes on at 1500, full boost at 2000, 1/2 boost at 2700.

its driving me crazy because i know its doing it and the wife thinks im losing my mind,

i know you petrol turbos have adjustable boost valves on the vacuum line to the turbo. can i unplug the stupid electric controller its got and just have the manual one.

that way i would have the boost all the way from 1500 to red line (not that it has ever been to red line since i have owned it, but you get my point).
and if so, what would i set it too?? i have heard 15psi, 18psi, 10psi. but what would the max be before reliability comes into the equation
