and even peak hp gains are meaningless without knowing the hp gain across the entire powerband range. just cuz something makes X-hp at 5300rpm doesnt mean you drive at a steady 5300rpm hahaha

Take it up with Chase and his team- I'm not saying I believe them. I'm telling you what their findings were and what they tout. You can see their development and dynos on their intake thread.

From what they are saying, it is the other way around. I find it hard to believe, but their report and dyno sheets claim 10whp gain from bone stock to just the intake, and an additional 7whp was found by Shiv when he tuned the prototype FRS. Again, not saying I believe them, but I am forwarding what they're touting
Guys I'm no spring chicken when it comes to autos- been wrenching since I could hold one and know enough to be wary of such claims. I've followed the development of the G/S intake since they started it, though, and knew it was a great piece for the money (group buy rate, at least

)
Plus, I sold the stock airbox and inlet for $100. So what's really $200, when people are spending upwards of 1k+ on catbacks. To each their own
