Find one additional point for Int and get Premeditation. Until you do that, any other changes you make are wrong, because the entire build is wrong. Any psi build without Premeditation is wrong. You can build without Force User, without Locus of Control. They're incredible feats, but you don't have to have them. But you have to have Premeditation, or else your build is wrong.
Dropping the Dex to lose Grenadier and throwing any leftover points into Con wouldn't be a bad choice. Having Sprint is awfully nice, though. Even with psi haste, there will be a lot of situations where you're glad to have the extra 30 movement points.
edit: I didn't even look at the build properly. Another fundamental problem here is that Strength-built brawlers are mostly poor builds, and strictly inferior to Dexterity-built brawlers. Gloves are light weapons and get AP cost reduction from Dexterity, so you get way, way more actions per turn. That more than makes up for the increased damage per hit of a Strength-built brawler.
