X2.. I would say that's totally wrong, the point of the getting your car tunned with SAFC is to tune it where it needs to be tuned, not like they were saying ^^^ ("-5 all the way, start from -2% slightly angle it lower around 4500-5000 i change it to -9% and from there to redline it's at 11%") That's bad advise, tuning isn't generic!!
