LFS version V is still the best for me because i can use the LFSTWEAK V and make my XFG go high Revs like the honda Vtec etc, and also making my car sound like it has a couple of throttle bodies on it, the same goes on for the XRT that i make it sound like a 3.0L V6 ford and tune the engine displacement in the tweak program then LFS lets my car really sound like a V6. i Will make a video to show you all how fast my cars is and how it sounds especially when i am doing burnouts with a ford motor.
I am Using Patch V Because u can still use the XRT there so i created a Sound for the XRT that Sounds like It Has ITB's/Weber's with K&N's, I can share it with you.
