Nelson tune vs Superchips

[silver01]

I would like to also know how much HP a Nelson Tune will give you on average?

It all depends on what you have to work with. The best tune will not work without supporting mods sometimes. Say you have a plugged cat convertor. The best tune in the world won't make HP. It's best if you work with your tuner to do supporting mods to get the most out of your tune. If your engine is in good condition, you have a good exhaust and cold air intake you can easily pick up 40 HP. Allen has a post on here telling us about how to pick up 100 hp on a budget.
