Properly tuned CIS will not run lean at 352RWHP.

It's easy to say EFI is great after you've spent thousands and lost a year (or more) of your life.

It's easy to say that CIS is not significantly inferior if you've never driven an EFI 930.
Problem is I have. The other problem is none of them were running right. I need to go for a ride in a primo tuned EFI 930. Any takers?

Now back to our regulary scheduled program ......
So why/how can EFI be so expensive? From what I have seen the sensors can be had for under a thousand. Hardware another grand, software ???? I don't get it, MegaSquirt can be had for <$3K, where and how can you tie up $40K in an EFI system? Labor? Tuning? Is a $40K EFI system that much better than a $10K system? How much of that money is not EFI but engine management?
