While getting a longer run does prove something the real proof for a mountain guy is how it works at elevation as we know. This isn't specifically a M forum but I don't know anyone regularly on here that is F chassis. Probably 75% of mountain guys that have done upgrades had a low elevation tune or box installed already. Unfortunately there was a lot of disappointed people when they got their "250+" tune to the hill. Nothing against flatland tuners, just unrealistic expectations for customers not knowing what they bought. Haven't done a lot of comparisons of dyno charts on the hill....ever. Last time I compared the "over 250hp" box on the hill I recorded it.....and put it on Evo's site.
Not down playing or raining on the the Speedwerx tuning parade, but when you post numbers like that on a forum mostly M chassis you know what the response will be. The exact same post on HCS would be met with a favorable response I'm sure. That being said I bet there are 3 guys on HCS that are M chassis lol.
