I consider myself "convinced enough" that I didn't think it was worth it to do another before/after dyno on this part (my last dyno being so old and all). The other charts and results people have already posted in that ungodly-long manifold thread seem pretty consistent with the reasonable explanation that longer intake runners = shift the torque peak down a bit.
Whether the small change is worth the cost, that's a pretty good question IMHO. But for my personal case, seeing as I'm not going to do forced induction and there's very few effective breathing mods left (basically the M370 that just went on, and the FI headers that I'm waiting in line for), I may as well go all the way and then get this final breathing config dyno tuned using my soon-to-arrive UpRev.
