Also when chipped how does it effect the fuel economy over standard in like for like situations....i appreciate it will be more thirsty when booting it, but how about normal running around?
Also, for those of you with after market springs fitted, does it smooth the ride out at lower speeds as my car seems harder on the arse than my S4 with H&R coilovers fitted.....which incidently is now for sale

Any advice is appreciated.
Phil.
oh and when do you need to start fitting uprated oil coolers?
