Sub.... What happens of you know the way to your location?
A remap drastically changes your car performance, and I use the benefit of that every journey without fail. But I have the mfd2 so I do have nav, just poverty spec! :-)
Remap.....
dunno about the RNS510 but RNS-E confers other advantages such as slightly better sound quality, SD card reader (my old Symphony II meant I only had a 6 CDC and no "modern" way of playing music) and just makes my interior look better/a nicer place to be. also just because i know where i'm going doesn't mean i know where the traffic jams are. my RNS-E has driven me around a sticky situtation or two before so sometimes it's on even if i know exactly where i'm headed
plus you gotta factor in that i graduated from a 1.6 MPI to a 2.0T so i still feel the 95% increase in power in a car that weighs exactly the same is plenty for the minute
.
don't get me wrong i'd imagine a remap does make a world of difference, but in this era of traffic cameras, coppers with a bee in their bonnet, high petrol costs and the like you still can't exploit the whole 197bhp on tap so what's the point of more? tbh after having had a remap planned for ages i don't think i'll get one on this car now. a bit of weight saving, a CAI and some of those aerodynamic tweaks and i think my car will be plenty fast for me until i can afford something that was designed to be quicker from the factory floor.
