Diablosport tuner for 2015 3.6 Altitude. Has anyone used this? If so, how is it? Not very experienced with these things. Had my Audi chipped from a dealer. Is this the same sort of thing or is it difficult to install/use for a non-experiened car person. Tried the Hypertech Interceptor and I'm not crazy about it. Not looking for anything crazy or a supercharger. Just a little boost and pep. Any info would be appreciated!
