Hey guys, Just a quick one, I'm getting a set of Nizpro Valve Springs installed some point in the very near future, do I need a tune immediatly, or am I right to drive around 'till I get my pump and injectors installed and then get the tune? Also, while I've got you, I have a Capa Flash Box that has previously been used on another car (1 life is used) am I able to use that on my car? Is there any way to tell if it's locked or not? Thanks, Michael.
