Question Occasional short engine hesitation

Sorry, had to edit below a little bit, I went out for a drive and it really happens on lower rpm's than I initially wrote. This below should be more correct now:


Now and then I get a short engine hesitation when I do this:

- short shift and get into fourth gear at around 1900-2000 rpm.

- go slowly from roughly 20-30% gas pedal to 60-80%

- rpm rises aprox. 500-600 more rpms

- then just slightly lift of the gas, just a tiny bit

I sometimes then get a sudden engine hesitation, shudder. Like if I had very quickly lifted of the gas to 0% and then pushed back up again. It's just a short hesitation and then the engine pulls correctly, correct for the pedal position. It also happens at the same rpms in third gear, the main thing seems to be low rpms and a bit of load, a slight upphill for example.

I've thought this is a consequence of the special ECU without air mass sensor the CSL uses. But maybe it shouldn't do this. So I'm very curious, anyone else have this issue?
