Yes but first return the tuning back to stock completely. To be honest though I would try and sell it. With the recent crack down on tuning the Black Maxx will bring you enough to cover a Autocal and CTS Insight.

Ndlbz, did you end up selling the black maxx or did you keep it and use it for just the monitor? been thinking of upgrading to EFI, also wondering what the difference was between the 2.

Wow, holy zombie thread.. The main difference between H&S and EFi is H&S is a canned tuner. This means it's the same tunes on every single truck no matter what upgrades you have done. EFi is completely customizable and you can adjust it to fit your upgrades needs.

I know what EFI is all about, I was just looking for feedback from somebody who switched from H&S to EFI
