I am having a problem with my afr on my truck. I swapped my maf and my bov so that the MAF would be after the bov on the charge pipe. The truck ran great the oppisite way but after a wot run it would stumble because of the air being let off the charge pipe after the maf read the info. So I changed them around sunday and got in the truck to drive it and my afr is the same at cruise but under boost the afr drops to a steady 10.9 and at wot in the 9's. Now keep in mind the tune has not been changed from when it ran great before. What do i need to look for.....my maf is reading 1.42g/cycl and the engine is only seeing 1.12 at tops.
The maf is connected to the tb so the air that it sees is definately going into the intake just not reading it correctly. Any help would be appriciated. Oh and how can i post my tune for you guys to see?
