If you consider that a con, then that's about it. I also know that since it draws a little more power it conflicted with my P3 vent gauge when it was polling the canbus, but running an analog line for it fixed the issue.

So, map 4 is now the new map 0, and map 0 is an underpowered version of the current map 0?
