ATS Engine up-grade package v1.3

Mod for ATS, an engine up-grade (tune) package for ATS rigs. I've been using this in my own rigs for a while now and I thought I'd share it with you all.

Don't expect unrealistic HP or torque ratings with these engines, they are what would be used in real-life engine (computer re-mapping) tunes. So far this mod upgrades engines for the following rigs;

Kenworth T680 (600 & 660HP)
Peterbilt 579 (600 & 660HP)
Kenworth W900 (660 & 720HP)
Kenworth T800.2016 (660 & 720HP)*
Peterbilt 389 (600, 660 & 720HP)
Freightliner Classic XL (660 & 720HP)
Volvo VNL670 (660 & 720HP)

Download [UPDATED] v1.3;
v1.1 - added T800 by GT-Mike
v1.2 - modified torque curves
v1.3 - added SCS Peterbilt 389
