OK just had my 2009 S3 remapped wth a Revo Stage1 map. Hmm i guess i wasn't exactly woo'd by it, i mean to start with it they switched it back to standard before i really noticed. Maybe as it's a hot day today too (about 23.5) displayed in car temp. That it wasnt so evident. going to test tonight when its cooler. Anyway one thing i did notice now is a whistle on full boost/throttle, not the sorta ultra high pitched turbo hiss, this is a slightly lower note more of a whistle. He did mention something about diaprams leaking on s3s maybe the recirc valve or something i can't remember now. Is the whistle normal after remap? Anyone else a bit underwhelmed by their stage 1?
