So iv’e never done racing and was wondering what are the basic for upgrading the cars, Really all power is it? And what about the tunes like, are they alot different from racing and drifting tunes? 
Any help would be appreciated
It’s not always about power, but it helps! Lol. The tunes are a lot different than any other tune for sure. I suggest downloading a tune at first to get a feel of what it can do. Then start playing around with your own tune to replicate it.
exactly yeti , drag tunes are really unique in comparison to circuit and drift tunes . just a question though are you looking to do fwd,rwd, or awd?
I would love some guidance on doing a Mercedes SLK 55AMG drag tune…in AWD it goes like a stabbed rat but in RWD it squirms about like a bag of squirrels lol and it hard to keep going in a straight line…please someone save me from this madness lol…I know this car can be competitive with its absolute brute power its just finding a way to get the power to the floor
