Maybe call CS and discuss it with them, maybe they can assist. FE lives in KC, maybe he can help.
I'll say this, but don't be offended, I think you were used to a very strong/overssmoked profile. Not that it's bad, just that you were used to a very strong profile.
For people that are used to a STRONG wood smoke (oversmoked) you won't get that it an FE.
Sorry to say, but that's the truth. I'm not sure to advise you to stay with what you bought or go with something else to match that profile. You've been able to achieve more smoke, but you can't oversmoke in an FE. Not without building a log fire in the bottom and that's not the way to go.
CS has a return policy. It's a tough choice and I'm not sure what out there would give you an oversmoked profile in a small, NSF rated smoker.
It's too late now, but there's a lot of info here in the forums to help with the decisions (for future users).
The problem is there is no way for us to know your existing smoke profile without tasting it.
Sorry it can't match that profile.
