I took the schematic drawing PaleMelanesian provided and overlaid the template in the GIMP. It looks like you want to keep the spoiler, but if you can do an after/before/after test, by all means do.
You've decided to kill the spoiler in pursuit of mpg.
Well, that really doesn't make sense to me. You should at least do a before-and-after coastdown test so you (and we) know whether you've made the right decision.

I will remove the spoiler and store it. Right now I am very busy during the summer and will not have time to test. As soon as I am free and have time for my hobbies, I will return back to spoiler and test it and report.
