chip or programmer

You can go with either. It all really depends on your personal preference. I originally went with a tuner and it was nice because I could make some changes myself and only had to wait for an email to get an updated tune. Currently I use a chip so I can switch between programs very quickly without having to mess with anything other than flipping a switch. Anytime I need a change I have to send the chip back to my tuner and he makes the changes. In my mind this is a good thing because I am not an expert with tuning and shouldn't be tinkering with my own tune anyways. Pick a tuner, give him a call and see what he recommends for you.

Nothing wrong with a "proper" chip for your application by itself. It's just that today all the suppliers want to sell you one of the available "programmers." The "programmers," however, do offer you great versatility in that you can do some things yourself - and many of the "tuners" will supply you with "new" tunes that you can download that attempt to match any changes you've make, as you need them. So if you plan on making many changes in the future, the programmers seem to have the advantage in that you won't need to have your chip re-done as you make changes.
