Does anyone know the approximate 0-60 time of a 200 20v with a tap1 chip or any ecu mod like it. I am interested how much it really does improve the speed.
Thanks!

no direct before/after on 20v, but there's numbers for a chipped 10v 200 with a 14.75 ET, and brand new 5kTQ's (pretty much same car) ran 16.1

20v's get a bigger boost than the 10v's from chipping, so by extrapolation you can figure "at least a second on 1/4 mile"? also see scott's note about better mid-range acceleration with chipped 200 20v vs. chipped UrS4.

i have his chip/spring in my old 200 10v - noticeable improvement and totally driveable.<ul><li><a href="http://www.sjmautotechnik.com/perform.html">SJM HP graphs etc.</a></li></ul>
