i have just put a BA MK 11 G220 on the road as a taxi and have installed a Prince Gas System (Direct Injection) and i love it. i have lost no power at all and with a 55ltr tank, i get 350 kms (AND ITS A TAXI). I also know of three other guys that have G220's with over 200,000 kms and thay still rave on about the Prince Gas System. Pro Gas in Clayton installed it for me. Only thing is, it comes with a price tag of around $4,500 but you do get $2,000 back with the grant.
