I personally don't think its a piece of shit. It's much better than an AFC, but not nearly as good as DSMLink. The E-manage does have the ability to control secondary injectors, and it works very well. You can have the secondaries come in and out with your boost level due to the provisional map sensor.

The E-Manage will not cure random multi-cylinder misfire. For that reason I strongly recommend DSMLink or AEM EMS in a 6-bolt swapped 2g.
