What's crazy is the difference in operating range listed by each manufacturer. Just looking at the intakes, you would think it would be much closer to being the same. Based on these numbers, I kinda feel like when using out of the box intake and heads, the TF intake and Eddy heads would be a good combo and the Eddy 340 intake and TF heads are a perfect match.
