Getting a superchip reburned to a different code is normally ~$75-150. This is for a GENERIC program. $100 for a generic program is decent but you will still want a custom tuned chip when you are done with your major mods.
A custom program from superchips will run you an assinine amount and is still not the best option. Yes this is on top of the chip, dyno time, and any earlier reburns.
The simple answer is look for someone that has the SCT software and broad tuning experience. An X-Cal is the best option because it gives at least minor self tuning ability ($350-400) and allows for full tuning ability. ($700)
