Boost issues?
« on: October 20, 2016, 12:22:50 am »
Hi
Can anybody diagnose my problem for me
I have a ko4 car and what it does at times (sometimes) its makes like a whirry sound like chikchickchick sound as soon as turbo supposed to kick and theres no power then after its passed that sound phase then boom full boost.
It only does it sometimes.
I thought it was a boost leak and got dv+ but realsied it cant be a leak as it only does it on lower rev range where turbo is supposed to kick and it doesnt do it higher range where most likely it would leak.
So any ideas guys? Its like it kind of holds back makes the noise and soon after just shoots off and sometimes its perfectly normal
Please help
Thanks
Thanks
