Yeah, exactly how
@Spork1569 said, his only 2 stages are with stock IC and without but max boost is set for 24.75 on pump and 26.5 on e30... but without going too deep into it, there's a lot more to it than just boost, the more added timing there is, the more power and added heat there is too. I'm making about just as much power on Tim's ethanol tune at 25 psi than I am on Jason's at 26.5 psi. But you can't tell by just positive corrections either, you have to know how the base maps are set too. And true that most bolt on's make very little additional power, it's 95%+ the IC upgrade that lets you tune more aggressively, but intakes do add a little power while exhaust absolutely none, I know I focused on a DV upgrade, step colder plugs and a hotside pipe and that's it other than a bit of intake mods... But Jason does take a list of all your mods too, to see if he can tweak his tune just a bit up front. You don't get any revisions, just a one-time safety check with the low price flash tune, if you want more power then you have to pay for a custom tune.
