this thread is great but can someone jus clarify few things for me, can we conclude that Helix can b the best FMIC. How about ETS? It has the most pressure drop but from the data posted by Michael @ ETS (If i rmber his name right) that it has the best ability to keep IAT low? I just bought one and it is sitting in the garage waiting to be installed... would definitely like to know what is the downside of higher pressure drop.. Can I not run a more aggressive map to "artifically keep the boost level high, so that it will be back to the PSI level I wanted despite the effect of pressure drop? Sorry about this noob question but Im a bit lost after reading so many people's different view and comments.
