hey i have had a 1990 m20 525i for a few months now and i am starting to look into mods. i was going to order a chip but a e30 guy i know told me that you could run m30 injectors and maf on a m20 but i wanted to get some input and suggestions before i ordered parts. i wasnt sure if i had to get a specific chip or something to support those mods if thats even possible. thanks
