Hi Luis,
I am a violinist, but I am curious if the methods I use would translate to a guitar. Generally, in my opinion, if left hand knows the note sequence well enough, moving the tempo should not be a problem. Many times I had very surprised students who were able to play a certain passage up to speed in lesson although they “have never played it fast before”. Sometimes I suggest that they play a portion of a piece/passage, etc… “as fast as the can” – sort of running downhill/wind in your hair feel and see what happens. When they trip up, we analyze: did you overthink or did your fingers were not sure where to go or something else. Depending on the answer we decide on a best way to address it. I also use slow -faster-even faster-fast-slow-slow structure to gradually move the tempo but always finish on slow to reemphasize the correct mechanics in the left hand. I hope this helps!
