well if someone is doing that they are intentionally misleading customers as to gains on their tune, which I hope it is safe to assume that neither Lethal or Whipple is doing. Can you source what you are saying about the Ford Performance packs, I had not seen that before. I know they state that you should use 91 octane. I would hope that anyone that is tuning any car much less a turbo is running premium. Regardless all I see is the start of a bunch of crying about blown 10r60s and how Ford wont warranty it......But something that certainly does matter is if the baseline is done using 87 octane and then the second dyno run is done using 93 octane with the tune. Not really an apples to apples comparison then. Ford performance is doing just that with their packs - showing pretty nice gains but only if you don't also factor in the octane difference before and after the tune.
