Vendor bash much? The extra clearance and adjustment room, as I already mentioned, is most likely for manufacturing tolerances, and if anything probably a safety margin so you don't hit anything if things get a little out of adjustment over time. Meaning it won't be universally available, usable, or safe. UpRev's been working hard on tuning our ECU for a long time, so it's kinda hard to claim they don't care either. If you'd like to purchase your own crate engine from Nissan for 8K to screw around and damage something and maybe figure out a trick to gain +3rwhp sometimes for some engines when the stars align, feel free
