That's exactly why I took averages of regularly tuned FI'd cars!

Otherwise I would have used the 295HP Turbo 2.5L & S/C 2.5L dynos as a comparison. However I know those were maxed out tunes and not a true representation of a normal tune running on 91 octane tractor fuel.
In some locations the high tune numbers would be valid because better fuel is available right at any pump!

So those numbers are VERY VALID for a true comparison.

Also the SHOShop 3L is a very valid comparison considering it was tuned on Kalifornia reformulated 91 octane POS fuel. The fact that it's overall power numbers averaged only down about 6% on HP & TQ show how well a well tuned 3L (even with the small valves) compares.
Then factor in one with larger valves, better head porting, ~11.5 CR and with 92-93 octane available at the pump and the overall numbers would be Very close for comparison! No waiting for boost required either!
