Boost problem

Post by mattykerby01 » Sun Jan 30, 2011 11:55 am

Hi,
Just started to get a boost problem on light throttle. When i reach about 10psi the boost keeps dropping to 5 psi then back up to 10psi, then 5 then 10 and so on.

Plus on full throttle i am seeing between 25-28psi - far too high !

Any ideas ?
