My friend drives a 99 Civic EX(I/H/E), he recently had his car converted from an automatic to a manual. When he went to the track in his auto, he ran a 17.41(SLOW). After the conversion, he ran a 15.67, thats a HUGE difference. Is that normal for Hondas autos to run THAT slow?? I knew manuals were faster, but not enough to take that much time off.
