Cobb probably won't tell us if the "access port" is a fancy name for an adapter.
The new airbox and muffler delete may not affect the car's tune by a radical amount, unless there are sensors somewhere looking for a specific number.
Example: adding a turbo to some cars causes the rear exhaust sensor on some cars to get a reading that there is more air coming out than is going in. One solution for some cars is to start adding resistors in the rear wire until the sensor gets happy again.
One reason I like carburetors, and I don't have a computer running anything, and I have no sensors.
I would install the parts you ordered and see if you detect that the car is running differently. Their last sentence sorta says that.
If not satisfied,
Plan B:
I would also look for a dyno shop and ask about dyno tuning. Most dyno shops plug a laptop into your car and set fuel air, etc for several sets of tune. and, if it's your computer, you can change things on your own car,
picking the tune that you want to run at the moment.
An experienced dyno shop may have a good idea and maybe programs they paid for to set up your car and many others as a package they bought as a cost of doing business.

It's mostly stock and will likely remain mostly so since I'm not the racing type, but I'm intrested in tweeking and peaking it a little...
I've just ordered an Ingen Evolution air box and am eyeballing a couple axel back muffler delete options.
I've already installed the Whiteline rear bushings and have the RSE Yellow springs.
What I'm trying to figure out is if someone can tune my car for the new airbox and muffler delete without my having to buy a Cobb Accessport. (they aren't cheap...)
