As a matter of curiosity, I loaded a VE map from one of the 300KW Holden Sedans and was pleasently surprised at the results. It seems the Holden is a good match for my head and cam car running in speed density. Except for the idle trims being rich at around -8, all other areas are falling in line, +5 to -5.
After putting some miles on the car, I had very LITTLE tweaking to do to get it tuned.
