Hi Graham, Its one of these
mumby developements controllers. Ill check it again but i did notice it has a plastic ball in it and not metal which i thought was a little naff although its moving freely.
I took the screw out as far as is on the pic on the ebay sellers page just with a few threads left.
Yeh pretty sure the hoses are correct although certainly going to check again.
Oh very happy with the chip by the way... thanks for that
and once this overboosting problem is fixed it will be great
