Hi All
New here and new to ford 7.3s. I have a e350 7.3 2003. I bought the OBDMX scan tool. I like knowing whats going on with my vehicles. The van has been converted to 4x4 and is a bit of an expedition vehicle so important to know that. Here are my questions.
When going up hill especially big steep hills the more power the van uses I get this vacuum cleaner sound. The more gas I give it the louder it gets. Almost like a small jet engine. I know the high pitch whine of a turbo this is much deeper and louder. Someone told me they thought it might be the waste gate. Is this what it is? Is this normal?
My other question is I have not been able to find how much boost is normal. Using the obdmx tool at most em getting 9.5 psi and that is going up a solid hill and pedal to the metal. is this correct?
thanks in advance
