The details are in the title, has anyone here made the successful jump from a 7427 TBI setup to either/or a 7427 MPFI/TBI+MAF system? I am starting to get the TBI dialed pretty good and wanted to go MPFI, edelbrock makes a MPFI intake manifold for my motor so when I did the motor build I used the stock cast iron to save $ while we tuned out the bugs. I know the basics of converting the PCM to run 8 injectors vs 2, I'm just wondering if anyone had any real-life advice to add? I'm also looking to convert from speed density to a MAF based system either before or after the MPFI switch, so any advice in that area would be great as well.
