I want to hook up my nitrous. How much should I expect to pay for the full install (with all the safety mods too) ?!

Do you need to tune the ecu or will the lt1 zex setup that came with the "brain box" be enough? Its a 125 dry shot.

How much per pound does it cost to fill up my tank? Thanks guys ---

 

N20 refills will run anywhere from $3.00 to $6.00 per pound.

Shops around me are charging 5.00$ ish. Some individuals refill and charge less than this.
