It's not even close to being as good as a custom tune! There are a bunch of guys on here who HAD hypercraps, diablows and stuff. They will all tell you that it was night and day difference going with a custom tune. There are so many more parameters that can be adjusted than what the handhelds give you. It's worth it, I promise...
