My mistake, I misunderstood your question.
What the other guys are saying is pretty good. I always liked Dbol for a plateau buster, much more so than I like it as some sort of a kick start. Nothing wrong with that or anything but when you hit a plateau this is where Dbol can really shine.
As far as upping the test, like tbombz said 250mg jumps is the way to go. Any less is worthless in this situation.
A cycle I always liked that kept things going fresh:
(BTW, the weeks are just a reference, so to speak)
Wk 1-6 Dbol
Wk 1-12 Deca
Wk 10-15 Dbol
Wk 8-20 Tren
Wk 1-20 Testosterone
