Yesterday I dynoed my recently installed JDM-intake manifold. Instead of having power drop off like an anvil at 5400rpms, my power carried straight to the 6500rpm rev-limiter. I gained ~7fwhp (189fwhp now) and overall I gained 53fwhp and 46fwtq at 6500rpms vs the stock manifold. I'm pumped to say the least. I had no idea this thing would make such an improvement.
