Paccar MX-13 tuning

[Black sheep freight]

I plan to run flatbed with this truck, grossing upto 80k, and sometimes substantially less, and I don't tend to run around like a chook with its head cutoff so while 15/16l would be nice it's overkill.

I've pm'd unilevers but will also hit up gearhead, and see if they have or can recommend a tune to suit. I'm aware of the other options out there but as has been seen in the isx world some of the quality of these tunes is questionable at best...

Lastly certainly would keep the Vgt and would run a mile from anyone who suggested switching to a fixed geometry turbo in this application.
