We do need to know some bench marks.
What dose a turbo motor with 7/1 compression running .8 or 1 bar should expect to be:
At idle,
On boost,
On the freeway
John makes a good point about variations in heat between cylinders.
We also have various with air flow and fuel delivery with each cylinder.
There is also increased sensitivity at different RPM depending on the cam, and actual AFR we all know varies a lot on a modified CIS 930 accross the RPM range.
Add to that the fact that these cars have little to no compensating features and that is a lot of exposure.
So when someone says they make more power at 12.2/1 AFR or at -27 deg advance they are running closer to the line. If in good balanced tune they may be ok. If not...
