These claims are rubbish.  They are total assumptions.  If one does the math
with these clames, that is a 54HP increase.  BS, I say.  Prove it on the
dyno not by seat of the pants.  A lot of those improvements would be great
for longevity, but you have been sold a lot of snake oil.

It is great to try to improve but to claim these sort of HP gains with
NOTHING to back it up, is a different story.

What happenned to dyno results?>
