Hey Migraine, the "chip" you are referring to is actually a module that plugs in between the ECM (the computer) and the wiring harness. It alters the information the ECM receives, kind of like tricking it. Generally they change the spark curve (more advance) and the fuel settings (leaner). They can also change the limits for rev limter, speed limiter and shift points, if its an automatic. Superchips and Diablo are just names that come to mind. Hope this helps. Tim.:s3

Since you have a 98 GT. I was wondering if you knew how much HP they had in 98... And Do you know how much the insurance raises from 98-99?? I am guessing it was a decent sized leap.

Next Upgrades....

After you got all the Superchip stuff done... you might want to consider a MSD Ignition...

Sounds like you're building one mean @$$ pony. :)
