Using W.I. I had managed to run my old Calibra down to almost 14:1 under high boost.
That is regarded as extremely lean by the standards of normal tuning, but it wasn't in that case. Max power with W.I. was at 13.5:1, instead of the 'usual' 12.5:1, so yes, you CAN lean it a bit while W.I. is operating.
The trouble is to make sure you have an 'exit' strategy in case the W.I. system fails.
Calling the AA is not a good one :lol:
