A 15.9 STOCK???

That's unreal. It looks like you got the pick of the litter. Have you dynoed it stock? I bet you're pulling about 115 stock.

The Zetec engine is VERY responsive to mods. With the mods I have ( CAI, MAF, UDP, TB, exhaust, cam gears) I have gained 19HP over stock.

Sorry for not replying sooner guys, as you can see Im new to this Forum and just getting the hang of it.
Yes my ZX3 did 15.9, stock, at the California Speedway (Fontana). Best pick of the litter? I really think so, 'cuz Ive spanked many of other Focus' when I was stock and now that I have a coouple of boltons: Exhaust, intake, pulley, ported throttle body, 14in LX rims with Falken "super sticky" Azenis, B&M short shifter.
