    Looking for some guidance if possible, I went for a remap last year on a 1.9 TDI 105PD but couldn’t go ahead due to it over boosting.

    I was typically getting up to 22psi, I’ve gone ahead with a mr muscle clean on the weekend and I’m now getting up to 18.5psi

    My question is, what’s normal for a stock Garret GT1646V on a 1.9 TDI PD105?

    I’m toying with the idea of upgrading the turbo to something from a PD130 as I believe the GT1646V is a bit crap.
