I recently put a Quadzilla scout monitor on my A pillar. Looks nice and i can see what the truck is doing wile towing ect ect. i ran into a problem reading the Boost pressure. Seems the OBDII is saying i only have 22 lb of boost. I know i have more, i roll into throttle hit 22 lb then push more, truck takes off like a bat outa hell and the boost stays 22 lb. I have an AFE Cold Air and filter. And traded the stock muffler for a beter flowing banks. Ive tried many ways to get over 22# with no luck what so ever. Being that the scout only reads what the ecm reads perhaps the truck ECM is fualty. Anyone ever here of this and if so, whats the fix?

 

you can get a mechanical guage, and find out for yourself....alot cheaper than replacing the ECM too

 

35 psi, i reflashed it still reads 22@ the 16 pin
