Well after playing around today I found out that I had the code wrong to read Exhaust Back Pressure. I guess thats why I thought that 750 psi was very high LOL. Now MAP reads 13.9 and Baro. reads 13.9 EBP reads 14.1. Thanks for the quick help. Is there a range that it should stay in? (LOW to HIGH)
Does anyone know if I cut out my converter up front on my 01 expedition 5.4 will it damage my engine / performance/ mpg
Probably not, the only reason your back pressure will be affected on a gasser is if you lost the exhaust scavenging effect by installing too large diameter of exhaust. If anything your vehicle will "flow" better without the restriction, but it will make you illegal for emmisions testing.

yes you will have issues. o2 2/1 and 02 2/2 will not read correctly and it will drive your fuel trims. this will cause a loss in mpg and a check engine light along with running to lean.
