Viper GTS ’13

This tune started off as the Viper ACR tune, so visually it’s similar to that (Wing Type C/Flat Floors/Aero kit type C/Mirrors (Other)). I wanted to experiment with a full-power tune, however, and I found that the ACR tune couldn’t cope. This motivated me to mess around with the tune, and ended up with this. My colour choice for this car was inspired by this TopGear article, which made me want to buy the car in the first place. It’s a tune that I’ve had nearly perfect for ages, but have stayed away from for a while, due to having other tunes to work on. When I finally came back to it recently, I spent more time than I should have messing with it, but here it is; a full-power, usable Viper tune. It handles like a dream with insanely fast lap times. Due to the huge power, larger tracks is where it really shines. However, make sure to watch your throttle on exiting tight turns as you can spin the tires very easily if you are not careful. Enjoy!

    Great tune!!! I really like Vipers and am always on the look out for a good tune for one. The handling is spot on,I like the trans set up too and as you said easy on the throttle out of the curves. Try it out on this track it drives great on it!

    If works with the 15 anniv. edition?

    • It is hard to say without testing it. Usually similar cars will work with similar tunes, however, it may not be exact with the numbers. Close enough usually still improves them, though.

        Ok, I’ll give it a try. Thanks for the fast reply, I was actually very surprised of that.
        I don’t have GT Sport but keep up with the great work!
