Has everyone here heard of Fitech? i've been in touch with them getting information on a throttle body gas injection set up. They recommend their 400 hp set up which at simply below $800 is their least costly set up. it might also require their gasoline command middle which adds $four hundred. this would be as opposed to placing an excessive pressure pump within the tank and walking a return line. It is supposed to self-learn after preliminary installation. At $1200 for a complete EFI machine i'm very tempted. They appear to have a first rate following and their merchandise are being offered via Jegs.
