not really it will let the engine breath better for sure , dont want to go any further than stage 1 cause , 1 ; plenty of power for me , custom code is a great stage 1 map and un like the ed30 it will be useable in the S3 , 2: i want to keep my clutch !!!!
i m not a figures type (bhp) i know when a car feels right and imo CC stage 1 power delivery in the 2.0 tfsi is brilliant , ive been in stage 2 + cars and they may just have an edge but nothing to write home about
The thing is I do not think stage 2 would be any harder on your clutch, in fact it may be a little easier on it
Let me explain -
Torque is what kills clutches and the time a clutch will be under the most strain is when you go WOT in a high gear at low revs. The standard exhaust creates more back pressure on the turbo than an upgraded 3" exhaust. This extra back pressure means the engine will actually make more torque at lower revs than an upgraded exhaust. An upgraded exhaust will make better top end power and at this point the clutch will not be under so much strain.
Stage 2+ is a different ball game however as the uprated HPFP allows much better mid range torqe due to their being no fuel delivery limitations.
My advice would be that if you want a DP then get stage 2 as well. Anybody with a remapped car should try to hold back from flooring it in 4/5/6th gear at low revs in order to preserve the clutch.
