In Holland (near Eindhoven) lives Gerrie Knubben.
It's the best in Europe! And not very expensive!
He works in private for rallyteam's from Holland, Germany, Belgium etc. He is also a MASTER in mapping a Cossie
He mapped and build the turbo from my previous Saff 4x4 , it made 345 Bhp and 560 Nm Torque @ 1.7 bar on greens and did not run lean !!
The turbo was build to last 2.4 bar (+- 375 Bhp / 600 Nm Torque it was a special spec. T03 turbo from his own design)
