The gain was with stock intakes, but was in the south east so temperatures would have been substantially cooler (also wasn't in the summer).
From what I gathered the FI exhaust netted +23RWHP from HFC and their CBE. However theirs was done on the same day, not weeks apart. Theirs was also tested in substantially hotter weather.
I suspect that if we see guys with the FI setups post up their before and after dynos you'll see the numbers will be probably pretty close to that of the Stillen setup. I don't see how, by design (but i'm no expert), the FI exhaust wouldn't produce the same power levels of say the Stillen.

It's incredible that people actually still believe the dyno numbers from that. No way the stillen makes that much with a y pipe. The dyno needs to be done on THE SAME car stock, then put the stillen on and dyno. Which is exactly what F.I. has done which is WAY more credible results.
