just to clear i dont mean 300hp upgrade or 500hp upgrade... i mean stages

 

Since prices vary GREATLY on the manufacturer, just add your prices for the stages:

i dont think there really is any set stages, just upgrades with consequences for bad judgement (over boosting or over taxing your fuel system). stock ignition should beable to handle quite a bit (as far as how much average guys are willing to spend).
