Well worth the money

The other review with a low rating is not to be taken seriously.
Yes, with a basic OTS map for a vehicle with no modifications you won't see a ton of gains; however, not only does the Accessport allow you the option of flashing tunes to the ECU when you make major or even minor modifications, it also allows you to monitor crucial data generated by the ECU so that you're more aware of what's going on with your engine as a whole.

Currently I'm having some issues with my thermostat being stuck open and I'm using it to monitor my coolant temperature to make sure it doesn't decide to get stuck closed instead before I get it replaced.
You can read and clear your check engine codes so that you can perform your own diagnostics and more targeted repairs if needed.
You can use the Accessport to pull a full datalog of your engine behavior during normal operation or under specific conditions either for tuning purposes or to try and diagnose the source of a problem you may be having.

Really it's a small price to pay for the various options that it opens for you, and if you're planning on doing any aftermarket modifications or just want to maximize your gains on the factory hardware, you're going to need one of these for the tuning process.

Really easy to use, interface is very straightforward, the screen is easily read, and the supplied OBD2 connector cable is long enough you can route it pretty much any way you wish whether you just want to bundle it up and stash it in a cubby in the dash or you want to route it discretely behind everything.

Get it, it's all good and well worth it.

Opens up opportunity

Dont listen to Jesse, yes if you just get the port its only a little more HP. But it allows you to be-able to install more major mods and aftermarket bolt-ons in the future.

Even getting an sftermarket sirbox requires a tune on this car, so this thing is worth thr money

Lotta money for a few hp
