Right now I'm running a PZEV 24# injector, Pro-M 70mm MAF with a Pro-M MAFS tuned for 24# injectors.
I have a stock zetec tube, a stock SVT tube, a 74mm tube and a Pro-M MAFS tuned for 19# injectors. Which are left over parts from 'fooling' the ECU with the change to E-85, worked pretty well BTW.
Don't "think outside the box".
There is no box.
