[QUOTE="RedVenom48, post: 15673642, member: 166576"] If it was running fine before but after the dyno tune and now its not, my opinion is that its something in the tune. Agreed that those codes shouldnt be popping up. P0102 could be whats throwing everything off. Possibly a failed MAF and its in limp mode because of it. Check the connector for corrosion or anything that looks abnormal. Also the P0462 and P1234 could have a limp mode enabled condition as well. But, since youre on a control pack with stand alone fuel system, those parameters shouldnt even be on. This is now just pure speculation on my part, but its possible the tune got set up at the dyno with GT500 parameters so its looking for FPDM and sender signal for a 2007. Obviously there is no such provision on a custom build as yours. Your BEST bet is to data log with the X4. Email VMP and ask them for their data log config file and load it into the x4. Ask them what kind of drive cycles they want to have you do. Ford may also have some parameters they want on or off going forward. Sorry this is happening, sounds like you have a bitching F100 there!
