Ok so this is the Code my pickup is throwing. P0470 Backpressure Sensor Circuit Error. Here is my question. 1999 Ford F-250 7.3L AFE Stage 2 Intake with 4" Exhaust, Edge CS. I'm getting low boost numbers like between 6-12 WOT. Could this Back Pressure deal be the Prob? I've checked the up pipes and they are good can't find any leaks. So the truck runs fine Turbo sounds like it Spools up Fast. The only thing is the low boost numbers and this code. Any Tips Suggestions oh ya and how to fix it?
