And look how much different the numbers are with a big change in outside air temp. Yes 30 may be "to high" but with knock sensor at 0 there should be no cause for worry.

Good example but this is just one vehicle, we also talk about failures but with AM there have been failures with just basic N/A mods. When we look at Lund, VMP and the like the failures have been caused when pushing the stock block to the limit.
When a company doesn't have the ability to tune a car when going F/I or anything above 100 shot of nitrous I think this is saying something. The don't have the data record to write these tunes. I very well think none of their tunes are custom... rather they're just pulling from the record books.
