I went from 256 to 324 without VVEL tuning which is 68whp more and let assume Mike had exactly 280whp as a baseline.. he got +62whp up to 342whp
the biggest difference between him and my setup is the oversized TB other than that the rest is pretty similar.

It's worth it to take some advice I heard once from a very wise man about how to compare dyno numbers.

But if you must, account for some of the potential differences...by watching percentages.

If, for instance, we choose to compare mike's gains to yours, say...
(342-280)/280~= 22.1% gain
(324-256)/256~= 26.6% gain

The SAE guys need to develop better corrections for their estimates...  |
And this is why I'm always loathe to compare numbers.
