martyh, i have had two peeps map my car in the time ive had mine and there is nothing generic about the maps, all maps are tailored to how the owners likes the car to act in terms of how the boost comes on, if they want pops and bangs, additional map for better fuel economy etc, dont also forget that people have different specs or you can have two cars with the same spec using different parts ( stage one tuning e.g panel filter or induction kit, 3 port or boost controller, etc) and cause of the parts the car may act differently to the other.
there you go rob
at the end of the day you spend big money or save yourself loads of money by listening to those who have done it and if quality second had parts come up then buy them like i have apart from the 3 port and bov everything else is second hand parts and ive spent around £700 total modding mine where as others have spent £2000 to get to the same spec as me.
bov = £70
hks panel filter = free
hks down pipe = £30
hks super drager =£50
performance friction discs and pads =£300
3 port = £70?
decat and fuel pump on car already as is the newly found tracker

eibach springs =£35
e9 bilstein shocks =£55
2x remap for different stages
carbon fibre front lip spoiler = free just rebuilt it and painted
air box mod= free just time to do
and other bits
ask, listen to what people recommend, buy second hand parts and clean them up, only buy what you need to buy and only buy new if you have to and if someone local is upping power on theirs and selling bits and they are the bits you need then get them ( like me)
