Who would you recommend? Revo is interesting as it's stealthy, so I hear.
Does anyone custom map and take you out on the road while hooked up to a computer?
Pal of mine had his CRX with Nitrous mapped like that, added launch control while they were kicking it round!
Have a look at the sponsors on here.
What do you mean by stealthy?
Any mapper that doesn't have a rolling road will probably do it like that
