Pros: Fun.
Cons: Not much for a stage 1. It's a software map only so doesn't require any hardware changes. Turbos have an overhead built in which mappers exploit. For my CR170 it was well worth it. Insurance went up £30 for the year and they didn't seem fussed I'd done it at all.
I think the important part of any map is yes, more power puts more strain on the clutch, turbo, etc. However, do you plan on redlining it off every set of traffic lights and going for 0-60 dragy times? If not then generally you won't be using more than stock power... but the extra is there if you need it. But TBH if your driving like that all the time anyway, even with a stock map your in for lower lifespan on parts.
The only warning I would give is I'm not sure on that particular model. But if you have a DPF fitted, the DPF will have to cope with the extra soot and it will shorten the life of the DPF as it can only handle a finite amount of soot.
