I have recently bought an S3 (225BHP) which has had a stage 1 Revo remap.
The car also has a Miltek cat-back, CDA filter and Samco silicon hoses.
I was toying with the idea of moving to a Stage 2 revo. Has anybody had one of these? Does it make a big difference? I dont have one of the revo controller boxes, would I need one if I did the stage 2?
Thanks in advance.
