thanks for your time, Bob Watkins Glen NY
You certainly live in a great place!

What you do is going to depend an several things
what do you use the car for?
how much $ are you willing to spend?
how much noise do you want to put up w/?
other mads?

In general it's best to use a custom chip burned from #s generated on a dyno or from using an LM1 or such.

The Motronic does have a limited ability to compensate for minor exhaust changes though.

If you go to a full header setup a chip would certainly be best

Steve Wong has a great rep and also has some off the shelf chips that may be all you need, 911 Chips
