what is a flat
#12
i agree with dieselcrawler 100% i turned up my 1992 f350 up 1.5 flats, and yes it smoked nice and i loved it but it gave me issues not long after, i only turned up the pump on my second idi 1 flat and it was fine with still a nice amount of smoke, unless you have the money for a rebuild get a pyro and be gentle if ur gona raise it higher then 1 flat
