Transmission shift management maybe?

It changes the shift points slightly (for power or comfort). Drive it in whichever you like the feel of better, Had a few XJs and each one varied. After 19 they just hard wired it in :power" mode from the factory.

Yep. Power holds a gear longer to get more hp at higher rpms, comfort downshifts sooner. Just try it, you'll feel the difference.

Mine HATES the comfort setting. It's completely gutless, always lugging the engine, and actually cost me a half a mpg.

(35s on 456s, ymmv)

And you always leave it on Power setting never take it off it strains the tranny to much and will cause it to fail with big tires.

I always left left mine on in my 91 from stock till I had 4.88's and 36"s
