ECUtek tuning by Eugene (ByThaBay) is going very well utilizing Full Speed-Density Tuning!
We are communicating with each other and as I send him data logs, they are analyzed and he makes necessary changes to make the car run nearly perfect while daily driving on the Z in the whole low RPM range, going up and down hills, curves, etc. I believe this is hard to achieve -- a very solid and nearly perfect adjustments as far as timing and air/fuel ratio so that it is not running too lean or too rich; but rather right on point nearly 100.

My long term fuel trims are around 98 average on the low side, and 103 - 105 on the high side which to me, since the target is to stay as close to 100 as possible...I feel extremely safe with his tuning and the way my car runs as I believe what made my car go kaboom back in Feb was partly the car running too lean and eventually it went kaboom!

Anyways, my car has a break in of 695 miles at the moment and I just started driving it last Saturday as well. About 7 days in and I'm nearly 700 miles! Wow!!!
~50 more miles and Eugene and I will be able to test the higher RPM ranges and make necessary air flow, timing, and Air/Fuel ratio adjustments up there. It will be exciting!

Stay tuned folks!

I really hope your 928 upgrades do not cause any oil coming out.
I have some tiny oil splashes still occurring in my vehicle for unknown reasons still.
It is appearing on the strut bar after a daily drive somewhere, and I don't know how it's happening so I will try to pin point the spot on where it's coming from by taping a white piece of paper on the strut bar to see what color the oil or whatever liquid it is -- if it is red then it is definitely coming from the supercharger, if it is black then that is most likely engine oil. If it is colorless then I don't know lol.
