Compression and leak down numbers, what are they?

Do you have a Bosch PST2? I would also check the following:

MAF
Air Temp sensor

Regards,
We haven't checked the ignition modules, we ran it on one coil at a time, so both work. Maybe if one module is a little bad and don't work over 4500 rpm.

Varioram is working, also just tried it with it removed (working i high rpm mode).

Compression is good, don't have the numbers, equal over all cylinders. Haven't done a leak down. Engine had a top end rebuild recently after an over rev that bent a few valves.

PST2 is that the "hammer"?
Error codes was checked at the dealer, nothing.
MAF is new
Air temp sensor, I don't remember if we changed or not.
