I can tell you that the Edelbrock tune seems pretty good. Everyone says it's very conservative which I totally get since they're providing the warranty, but the car still feels strong to me. Edelbrock's tech support is very quick to reply to emails also. I sent them a few scans and they came back and said everything looked good and my initial tune didn't need any changes. If you want the warranty, get their tune and deal with keeping it otherwise stock until the warranty runs out. If you don't care about the powertrain warranty, you'll surely get a more aggressive tune by having someone local to you that's reputable do the tune.
