problem with my EIII boost

[ce9a_evo]

I'm riding evo 3 engine on my wira , using stock turbine & 38mm tial wastegate. Previously i boosting max boost of 1.5bar , but dis few days i realize that my boost dropped from 1.5 to 1.3 bar. I'm using avcr to set my boost .

I toke out my banana and turbine and checked gasket & hose, there's no leaking .I've changed my boost controller soleniod to test boost but stil de same , cant reach up til 1.5 bar. but if i set de boost to 1.0 bar, de boost can maintain at 1.0 bar, seems lik normal. After all , my foreman change another manual boost controller for me and test , de boost able to reach up 1.5 again .

Til now i'm not sure izit de failure of my boost controller . is dis de symtom of my boost controller going to dead ? scratching my head now :stupid:

hope sifu can help

if its nt an exhaust leak, then its a boost leak, check ur BOV , and intercooler pipings
