Engine is a 2018 6.4 from a truck with the truck's tall runner intake manifold but using a 2010 5.7 ecu.
It has a 6.4 srt8 300c cam swapped in.
The stock 2010 truck 5.7 has somewhat similar 'VE SRV Mult' values (in picture below) as the 6.4 hemi 300c car tunes, where 4800+ rpm has increased values, but the 6.4 cars have much higher values around 5200 rpm (pictured below).
This VE SRV factor states: "Multiplies the VE if the SRV is open."
Oddly, I see that a stock 2018 6.4 hemi truck tune has the VE SRV Factor values all 1.00, this is the intake manifold the customer is using on their 6.4, does this mean those newer truck intake manifolds don't have a Short Runner Valve?
