Kleemann ECU upgrade
Well, I jumped on the Kleemann deal, just got the unit back and did the re-install. Had some CEL and sensor issues/bad idle initially, so I had to power down and reset everything a 2nd time, which got things back to normal.
Definitely has a more "connected" throttle feel, and more linear scope of travel with a feeling of solid power all thru the range of accel travel. Previously the car tended to treat accel inputs more abruptly, almost turbo-ish. I'll need a few more days to get accustomed to it and can report more later. Nicely, it does seem to interact a lot better with the transmission shift points, I dare say it's the perfect combo.
As for power increase, I haven't had a good block of time free to assess yet (work commute is super short - only 2 miles on suburban streets), but seems to have a strong peak torque. Should have some feedback by the weekend. As soon as I have my PLX Kiwi replaced, I'll be able to start logging data again.

Hi. When you say, "power down and reset everything a second time" what exactly did you do?
I may be having the same issue with rough idle after my Kleemann supercharger/header install.

He probably meant a hard reset, disconnecting the battery for 20 minutes. I've had to do the same before, solved the issue I was having.

I think I may try the plugs as you mentioned
