I did, yeah. So keep in mind my most recent driving with the 2860 was on 93 octane with aux fuel. The s280 feels faster and way more brutal until 5500RPM. The 2860 felt faster above 5500RPM and really pulled in 4th and 5th gears while the S280 still feels kind of sluggish in upper-4th and 5th gears. Obviously this is completely understandable given that I am not even on aux fuel yet for the S280.
The S280 feels better overall, I didn't realize how much I missed the low end torque.
