I sent my t3 to c r turbos. With a covering letter explaining I have a brand new -31 actuator ready to fit.
I ended up paying in the region of £560, turbo came back with a brand new actuator fitted.
No details of the spec of the T3 supplied, so I presume I have a stage2.
When I rang them up I spoke to somebody who I explained about the covering note i sent with the turbo explaining that I already had a new one, I then asked have I paid for this actuator fitted to the turbo you've sent me. They said NO.
So if you use c r, they give you a free actuator
I don't think so

Don't think I would use them again.
