And the codes I'd is throwing is p0453 evap p0462 fuel sender p1234 fuel pump driver module and the p0102 maf low voltage. The first three should not even come up on a control pack because they are turn off when the pcm is ship from ford racing I have a call into ford to see why they are coming up because I have a stand alone fuel system and the maf code show up because the maf count never changes but I have checked the maf connection and have changed the maf Yes have tried to reflash the tune several times I even drain all the e85 and went back to 93 tune when it was running fine and still does it so I don't think it is in the tune Sent from my iPhone using the [url=http://r.tapatalk.com/byo?rid=92568]svtperformance.com mobile app[/url] [/QUOTE]
