I just finished my cai yesterday and I raced my friend in his mustang. Hes got an automatic and he runs consistant 15.4 and I beat him down street in our own little track we use. We raced 2 times and I was just barely ahead of him each time. So I guess I can run a 15.3 or 15.4. Not too bad for an 88 maxima with not a whole lot done to it.I think the shift kit really helps bring the time down a bit.

 

by the way, I was running 15.8 or so before I did the custom cai. Definately a big improvement since it only cost me about $60.00 to do and a few hours to fabricate everything.
