[s-cars] Question About Chip Options

[Martin, Gary G]

Well, from hangin around this list for awhile, here is my observations
and opinion. First of all, Mihnea is one source for your quest. Active
on this list and good reviews from what I have heard. Secondly, TAP has
a less than stellar reputation. Probably most popular are MTM 1+ and
also Ned Ritchie at www.intendedacceleration.com. I have Ned's 1+ in my
200 20v. Very progessive, with about 22psi boost. MTM 1+ is more on/off
light switch type power with maybe a bit more boost. No personal
experience here. In my S4 I have a Wetterauer (www.chiptuning.com) also
very progessive with 21psi boost. Most stage 1 chips with no other
changes will yield about 50 HP gain. HTH

One piece of advice, stay away from Superchips! They don't know anything

about programming a Motronic ECU, they just raise security maps,
increase
the fuelling to over 20% over stock mixture and alter boost by means of
a
stiffer wastegate spring because finding the maps in the boost chip has
to
be too complicated for their highly skilled, top-notch (ahem) engineers.

HTH,
