What is your mod list? AM tunes are very conservative, but work great until you get to doing blowers, cams, nitrous, etc.
At that point, it's best to get a dyno tune. If you already have one of the above, it's best to contact a local dyno tuner and see if you can get one from them. I know locally you can get a dyno tune and SCT for ~$600.
