I was wondering if I have done enough mods for a PCM reprogram yet. Or if it should be done soon.

So far the list is as follows:

- Spark Plugs
- Spark Plug Wires
- Cold Air Intake
- Thermostat
- 3.4" S/C Pulley
- Just ordered Speed Daddy Headers today
- and contemplating S/C porting, just timid about drilling into my supercharger..

If this does qualify, where is the best bang for my buck?

Thanks
