I've seen a few posts about the cripple cap on the board of the actual car and after examining my celica with HORRIBLE range I noticed the new little brick.... notice the solder around it looks horrible... as though it were added after the fact...
I did remove it and got about 2 inches extra range.... so I'm not sure if it actually does anything.. but the solder DOES make it look like it was added after the fact for sure.
