03 S-Type R - 1st gear shifting @ 6100?

TCM update made no change at all. the new tires are very grippy so it didn't even really spin off the line for my 4 test runs 0-90. Each time it shifted right at 5500 to 2nd, and right at 5750 to 3rd.
However, on the way home, from a stop, it smoked 1st and shifted a little higher, around 5900... different road, less grip
My old tires would break loose 2nd gear when the weather was cold, and absolutely roast 1st. I wonder if the tires spinning have something to do with it "allowing" the transmission to shift higher?
Other thought- would an ECM update help?

it's not specifically mentioned on the list of service done, but that doesn't mean it wasn't done. hopefully they did
Forgot to mention this tidbit, Mike at Eurotoys said he could not change shift points with an ECU tune.

I would guess that the only way to get the R to shift at close to redline would be programming. Just curious if there is a real solid reason that Jaguar decided to do that to the R. My 3.0 runs all the way to redline in every gear. I ask since maybe they know of a limitation in the trans or rear when attached to the super charged engine and did it deliberately to stop any unwanted instances of self destruction.
(I recall that the only time I've heard of a ZF blowing up was when WhiteSTR blew his up)

Mafioso and I recently had a discussion on how to teach her later shifts. He affirmed what I had suspected due to the multitudes of attempts to launch her off the line without the ABS and ECU cutting in...You can coax her to shift near redline by not stomping on the pedal from a stop but stomping it down after rolling her a few feet off the line. This is especially more evident and important when wearing new rubber. Her old worn rubber allowed mean burn outs from a stop. Though this felt and looked cool, it hurts the time slip.
