Right while we're all arguing the right way to do the same end idea, can anyone help me! I want to know can I run my Zetec turbo on a Zetec ecu and obviously remap it or do I have to change to rs turbo ecu ofab,etc?! Iv seen st fez's running off remapped standard ecu's, I know they are slightly different but the principle of using the standard ecu is the same. Cheers guys
