Ps the Xr6 turbo does 0-60 in 5.6 seconds
No. its 5.1 0-62mph. Fastest independant test has it doing 0-62mph in 4.9 seconds, but I think this is a one off with a tailwind. 1/4 mile I have run a 12.87 stock with the fastest stock XR6 turbo recorded at 12.6. This is for a ZF equipped Auto.
XR6T is actually 212hp per tonne.
I don't know what mods you've done to get your ST to where it is, but I still find it hard to believe that a tune and exhaust only could yield a sub 5 second ST.
Other factors also come into play - FWD harder to launch cleanly compared to RWD, torque curve, where in the rev range is peak output produced. eg. peak power is produced in XR6T at 5250 rpms. But peak torque is produced from 1950 - 4500 rpm.
