i like the map system better for one reason if you want a blower or turbo just change out the map for a 2 bar or 3bar your fine with a maf or speed density it will lean out under full boost.but if you want just a daily driver nothing high hp then go for the one you posted.

 

I must admit those restotekspeed systems looks good, one of my major problems with EFI is that it normaly looks really ugly IMO.

 

retrotek and the efi hilborn are the only 2 aftermarket efi sets up ill run
