No Steve.. it's not theory. it's reality.

Here's one for you..

Go take a stock car and dyno it today..

Now go dyno it 3 weeks from now.. without
changing anything except time and possibly the
fuel if you get a new tankfull (likely). Also
wait another 2-3 weeks and do it a third time.

Come back to me with the results..

Although I already KNOW what you'll find..

You'll find a measurable CHANGE (up or down, can't
predict) in the power.. or the midrange torque
or both..

That's because you motor is ADAPTING to the
exact environmental conditions it finds at
the time you are driving (or testing) it.

(That's why I always say to go and test your
car, same day, same dyno.. it's also why
I tell people that dynoing these cars is
a waste of money for the average joe)

This horsesh*t about "returning to stock" is
getting ridiculous.. I've not intended to get
off on a rant here, but here goes:

I think I've probably dynoed more OBD-II BMWs
that this whole list combined with every other
tuner in the U.S.(spare Dinan).

I've DONE all this research for one reason and
one reason only.. to be SURE that when I tell
you something it is 100% true, and NOT bullshit.

(Yet every week, I have to defend myself against
someone with a fresh notion)

You or your friend simply as a private individual
cannot afford the amount of research that we've
done on these cars... unless you're both crazy
and independently wealthy.

As far as the "theory" it's PROVEN in PRACTICE.

I just got done assisting the owner of a forced
induction car who was having all sorts of little
nightmares with mixtures changing. When he
listened to me, he was able to RETUNE the car
himself and now his car runs better than any
of the lot from the well-known tuner he bought
his forced-induction kit from.

(Imagine that)

It really does come down to the fact of you either
listen to me, and believe what I say, or don't

If you don't, continue to throw money the way of
the dyno operators, so they can place more ads
and further the current "dyno mania" that really
does nothing by make the dyno operators rich.

Because it really does come down to that.

Most "average Joes".. heck, most "racers" can't
afford to spend the time and money on the needed
testing. Further, they don't have the scientific
knowledge to interpret the readings.

Yes, folks.. you really do need to INTERPRET the
readings to see what is going on. You need to
know how that particular breed of car behaves (or
not) on the dyno.

Some cars lose power 1st to 2nd run.. some gain.

Some cars adaption is so weak that they never
change power at all.. some is so active that
merely running it at the wrong midrange RPM for
a few minutes can throw off all the results of
your session!

It's sort of like YOU looking at your own CAT
scan trying to find the problem. It isn't
likely to yield any worthwhile results.
