Dynapack 5032.  I think it's the same one that APR has.

When you publish the results of your comparative runs, please make the
comparison based on measured power at the wheels, not calculated back to
some "hypothetical" brake horse power. This way we can concentrate on
differences between the chips, which is much more important than some
theoretical output figure that owes more to fuzzy math than science. You
should, of course, correct for changes in temperature, humidity and
atmospheric pressure.
What model dyno are you running this on?

Subject: [BiturboS4] Cross post: Chip shoot out in Chicago

Just in case some of you aren't on the S4chicago group.

It's almost time for the Chicago S4 Chip shootout.  Our dyno is due
this Monday!  Everyone has probably been wondering what type of
performance they are getting from their chip compared to other brands.
I know I've been pretty curious to see first hand.   We'll be using an
6-speed manual M-Box ecu car as the test car.  So I'll need volunteers
that have ecu with these chips: APR, ABT, MTM, Upsolute, Neuspeed and
whatever else that I may have forgotten.

All information that we will obtain will be posted of course on
Audiworld for others to review.
