[urq] Abt fuel distributor

[Bill Bennett]

CIS is too limited, if you are gonna spend money for a fuel system mod, 
spend it at Javads 034efi place, try using your laptop to change fuel or 
timing maps on a CIS Hartig system, ain't gonna happen, for less than 2 
large you can get SEFI, most bitching, more power, better mileage, did I 
mention more power, better MPG? all adjustable by the user? CIS is dead 
IMHO. Sorry yeah to me too, I love CIS
