Just to play devils advocate, almost everyone and all the reviews on American muscle are positive why would that be?
Typically the reviews are dead on for AM

When I wash and detail my car it feels faster and runs better, but it's not and doesn't its all perception

Placebo effect everyone is aware of it.

The reviews state gains and I don't see why it would say 10hp gain if its a load of ****. I'm swayed off buying it but I don't see why half people swear by it and say its a great bang for your buck and half say they are a waste.

It does give you a dyno proven 3-5 hp,
I saw someone post a b4 and after, for 60 bucks just get the thing but don't tell anyone
