yeah the difference is a minor one between Mk VI Gravitic Thruster and MK VI Total conversion Engine. Turns out very minor as my memory was a little off. the MK VI Total Conversion Engine thrust is 358000
Mk V TCE is 355000
Mk IV TCE is 352000
Mk III TCE is 320000.
very very minor differences.
I doubt that In Draco they will be even close to these thrust levels.
