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.
Most people will bump the size up to a 16x22. The difference in the cost of your garage is minimal compared to the extra space. The most common two car garage size on a Minneapolis or St Paul city lot is 20x22. 2-1/2 car garages start at 22x22 and go up in 2' increments. Western recomends building your garage as large as you feel comfortable. Three car garage designs will start at 30x22 and go up from there.
