i thought i would just add my experience to this even tho its not a skoda
2007 Seat Ibiza 1.4TDI ( AMF 75BHP)
Mods:
PD160 air intake
Greenpanel Filter
Custom Code Phase 1 Remap
Been running the car for roughly a year now with the remap and it really makes a huge difference! not had any problems yet at all
I got the car Mobile Roalling Roaded at GTI International 2009 ,Bearing in mind that it was very very warm that day and the engine was very warm when i went on the road it managed to Produce 105.6BHP and 182.7 lb/ft Torque ,Custom Code predicted 100-112BHP and 185 lb/ft Torque
A few people have said it will be producing slightly more than 105 , due to it being very warm and also mobile RR aint that accurate so i would like to think its closer to 110
