Just took the car for a spin, and had the boost gauge on. Anyway, i got my peak boost of 22psi on a revo stage 2 however it dropped very very quickly past its sustained of 17psi to aroun 10psi.

I dont think i have have boost leaks as i upgraded all the pipes and jubilee clipped them all? any suggestions?

re check all your pipes again mate to spike to 22psi then drop to 10psi its boosting fine just not holding so would suggest a leak check the intercooler also [Y] jubilee clips arent very good foor stage 2, my ic to tb hose has blown straight off under full load twice on me now due to crappy clamps [:mad:] could be the dv leaking also

Ko3s is a small turbo remember so it will find it hard to substance hi boost and due to heat the car will pull back boost any way.. Does sound normal .. Peaking and dropping off even mine dose that and I have a bigger turbo and intercooler ect .. So I fitted a meth kit to help in the Sumer 24psi all day lol temps are a killer on turbo cars...
