No I got rid of the power FC and went with a stock ECU from JDM OF MIAMI.

Also when getting into boost after a while I notice that white smoke comes out in a big puff after boosting and it really stinks bad if I have my windows down.

there is almost no shaft play at all so I wouldn't think turbo is bad. Could the person who put turbo on have put wrong restrictor on this? like the S14 Journal bearing restrictor?

how can I test if waste gate is bad?
