Massive newbie questions once more - 2002 1.8T AUM is booked in for Stage 1 with RTech in 3 weeks, flexpipe is leaking so ordered a decat 3" DP. RTech say to fit it ASAP, car won't go into limp mode but will have an engine management light on. They also said they'll map out the cat for no extra cost - brilliant!
So far my experience with RTech is they know their stuff, but I'd be interested to chat to someone about the decat and what happened before/after map. I'm terrified of screwing up my car, Dad is helping me out in a big way to fit stuff but his experience is older cars. Exhaust stuff is pretty basic mechanical knowledge though, I don't foresee huge problems.... Right?
Thanks to Prawn and Welly for their advice so far.xxx
