Hey guys im not sure what went wrong when i zipped up the previous mod yesterday, but I HAVE re-zipped & tested this version 2 of the Performance Upgrade Pack now.

Here it is fully working in game (1.43x) tested literally 5mins ago (6.31pm NZT, Jan 18 2022). My apologies for the mistake!!

C67 6.7 Liter Deisel V8 with Stage 1 Tune, made with sounds from real 6.7 V8's.
12 Speed trans for Heavy Hauling, matched to the engine torque curves.

All files built from scratch so there no conflicts with other mods.

Im not a 'PRO' modder obviously but i like the sound of this engine.

Please support my You Tube channel by liking the video below. My discord link is also there.

Enjoy & happy hauling.
