Just to be clear, stage 2 maps are written onto the same software that stage 1's are, you don't need to change that at all.
I don't know who "they" are, but if they only offer a stage 1 map then i would be wary of the quality of their work, you will often find people who are flogging crap generic maps that they've found somewhere and don't actually know how they work. There's a couple of good mappers on .net - mrwhippy, pro_steve and tb205gti.
Calling them stages is misleading, but the basic gist is this:
- "Stage 1" is just a remap. It will see you go up to 115-120bhp, can get as much as 130 if it's a very good map and you've done some basic supporting mods, such as de-cat, de-backbox, etc.
- "Stage 2" denotes some more extensive supporting mods, as detailed above by Padge. The term "stage 2" is usually associated with breathing-focussed mods, hence fmic, 2.5" straight-through exh, new intake system, hybrid turbo, etc. Again, you would need a new map to take advantage of the new mods.
- "Stage 3" (for anyone interested) would then be the fuelling side of things, so bigger fuel pump, different/modified injectors, higher pressure rail sensor, etc. This is the point at which you might need to think about different software for your ecu, or even a stand-alone management system (I wouldn't say it's necessary, but it's all a matter of preference and opinion). Even if you didn't want to go down that route you would still need another new map to match the mods.
