So, when I finally do get my 550 (see my other post - i'm actively shopping and it might be next week....), I'm going to want to tighten up the throttle response and tune it a bit, so I was looking at the ESSTuning N62B48.

But... I'm confused as to what it actually.... is? I mean, it talks about software, but ... how does it interface with the car? I would assume there'd be a module, or a cable, or some such thing.

Has anyone bought this before? I don't want to drop a grand on something only to find out I need to buy a $400 cable and a $300 chip or something.

basically you'll buy the tune and ess will ship you a cable and some software- that's what they did with my tune anyways. you can use the software and cable to download the tune to your car.

the tune only shows like +15 hp or so on pump, but you'll be able to run high octane fuel for even greater gains.

Yeah, with a 10.5 compression ration, I assumed I'd be running 91 or 93 octane anyway. I'm not really concerned with 15 horsepower, more just - I want the best driving experience. Snappy throttle, mainly, but I'd also like to play with it, you know =).
