I installed the Jet performance Module in about 40 minutes.Everything was included with the Module for installation (except the tools).I have noticed an in crease of about 400 RPM in my shifts and a .02 decrease in my 0-60 ET's.
This cage size is fine if your budgie is outside of the cage most of the time, but if you have a cage-confined budgie, it's going to be much too small to keep your bird happy and healthy. For two budgies, 39- by 20- by 32-inches is a recommended size.
I have two budgies who I keep in the same cage. I let them out of their cage everyday, but they spend most of their time inside their cage. The size of their cage is 19 inches long by 11.125 inches wide by 19.125 inches tall.
