From my previous thruster research (link at end) I noticed that all ships seemed to have the same ratio improvement in speed and turn time for A rated thrusters at 50% optimum mass, and the same held at other mass thruster combinations I had tested. So I decided to test a few ships across thruster grades AE at optimum mass ratios of 9050% (in 10% incriments). The following table summarises the improvements in performance over a ship operating at optimum mass (All thruster ratings have equal performance at their optimum mass)
Speed increases by the % shown. Turn time changes by [Turn time/(1+improvement%)]
The ships used for testing were: Hauler, Vulture, Clipper, ASP; not all ships were tested for all combinations but there was plenty of overlap.
The A(50%) figure has also been tested on Cobra, sidewinder and DBS as well as the above ships.
Note there is a degree of smoothing in the above table due to the limitations of measurement (speedometer only shows nearest m/s, turn rate is average of 10 rotations)

%change vs mass
Note that the speed and agility bonus have been decoupled unlike for the standard AE thrusters.

Understanding Thrusters in 2.1 outfitting screen:
With the new outfitting screens you can see better what thrusters do.
There are six thruster stats to consider. Minimum mass, optimum mass and maximum mass. Maximum multiplier, optimum multiplier and minimum multiplayer.
When your ship is at minimum mass you get the maximum multiplier applied to your speed and turn speed.
When your ship is at optimum mass you get the optimum multiplier.
As you get heavier you approach the minimum multiplier (not tested where this is may be maximum mass but that's very hard to reach).
The Engineer upgrade multiplies all three multipliers up b the same amount. so if you roll a +25%, a standard A rated drive will apply 1.125 minimum multiplier, 1.25 optimum multiplier and 1.45 maximum multiplier. (original values .90,1.00,1.16)
They seem to follow the same curves as the previous calculations so it's just a straight % boost to speed, acceleration and pitch.
