RE: Program questions
just checked its set to Automotive. and CPL was 3749 i think that crossrefs back to a 2733 before DPF updates.


so you are right i believe on turbo have to wait till daylight to read part numbers. and i have brought down my idle percents a bunch from the overlay to get the airflow down as it could float a stack of papers. 34%ish was at 59% from the overlay. still some air coming out but not near as much.

But on my top end im around 60% closed to get up to 38-39PSI range, think overlay was something like 52% and was only hitting 32PSI on a long hill.

I have never seen a truck need 60%+ for turbo position in any part of its tables under load unless something was still wrong somewhere mechanically.

even my prostar with its restrictive half-pint CAC, it only needs about 57% or so max. Any truck with a full sized CAC, it is no more than 54-55%. and big-nose trucks, it is far less.

Just stating this here as a reference for those who want a more proper perspective.
