mission:
for $9.00 you might as well try it, it seems fairly convincing with the free replacement and bla bla bla, I don't trust any of that stuff, but for the price it would be worth tryin if you don't know much about motors and increasing hp yourself. if u do buy it, let us know how it works
I personally would (and have) increased my timing.
one problem I have with that thing is the stock ecu has it's timing set for the temp of air that you actually run (and some other unrelated things), trickin it into "thinkin" what air is comin in doesn't do much.
but i say give her a shot anyway, hell you can hardly buy a cd for that much
