D-Jetronic Porsche 914 2.0L ECU, Bosch 0280000052

Hello everyone, since time and with this covid ... since 2019 a lot has happened, my 914 2055cc engine and the D-jet and special camshaft, so from Stuttgart with the Porsche club I learned how to make all the manifold pressure sensor settings according to the engine.
So now I replace the membranes. Since then my engine has been running like clockwork. this winter I disassemble again to put a new camshaft that I designed and I hope to get +- 140hp.
the membranes, I bought them in the USA, but it becomes too expensive.
Do you have an address in Germany?
thank you for reading me.
