Things also move slowly because so many people talk up products that have yet to be tested, then the "real" data comes out and people rubbish them because they didnt perform as well as what some guys on the internet say they should
sure the compressor map shows it will make more power, but simply saying the GTX blah blah WILL make more power than a Blah Blah is simply rubbish, they are only going to be slightly better and most of that will come from running a 58 trim comp wheel.
So until I see a few results back to back (and by that I mean run gt35R on dyno, take turbo off on the dyno and strap the GTX35R on and run on the dyno with nothing other than tuning changed), I will continue to be skeptical
