For 1 you can't post a link to the other forum on here. 2, I couldn't do it on this iPhone map if I wanted to. 3, show me the stock compressor map and then place my 440whp on it you can't do that either. Of course my goal is to be in the compressors efficiency range but if I still see gains slightly outside of the efficiency range I will continue to increase boost exactly how everyone has done it on stock turbos. So yes you may be correct in saying it is impossible to reach 500whp and still be in the turbos efficiency range, with that being said, no one pushing over 16psi is in the stock turbos efficiency range either. I plan to push the hybrids as far as I can until gain are negligible then back the boost down some for efficiency.
