Message	So those are Sport600's with BB cartridges and Greg D. split downpipes? Where does full boost actually hit? It appears from the dyno that it's around 4500-4600 rpms. If so, that's very interesting, in that I have regular old Sport 600's with Random Tech 3" downpipes and I build full boost at the exact same spot. The reason I ask is that Greg D. (and others) made claims that the split pipe design on his downpipes would allow the turbos to spool up about 500rpm faster. If that is true, then I will buy some, but if I'm reading your dyno correctly it doesn't appear to be that way. Any input is appreciated. Not saying the claims are true or not.. just want your perspective if I'm reading something wrong. Thanks,
