anyone try this Z1 module adds up to 20 HP ??
More info on this "Z1 module"? It sounds fishy to me because you didn't
provide any information--is this an intake mod, an exhaust mod, a
miscellaneous engine mod, a turbo kit? Where's a website that shows
pictures of this "Z1 module" installed in a Hyundai automobile and
includes before-and-after dyno graphs? The headers on your message say
this was posted from near Chicago, Illinois--has a Hyundai group near
there been talking about some parts with "Z1" in their model#s?
You *can* get 20 more HP out of a V6 Tiburon without breaking the bank
or your back. Cold-air intake kit+K&N filter+replace OEM exhaust back
from the catalytic converter = ~25 more HP for ~$1000. Received
wisdom from the Taurus SHO people says the best, cheapest way to get
more power out of a car is to open up the intake and open up the
exhaust. Anything else (forced induction, N2O, etc) gets expensive
quickly.
