There doesn't seem to be much going on here in the UK, but post September (keep or trade decision time), I would be happy to be proved wrong...

Are you being serious, there's plenty of us over here with VAP tunes, pulleys, cats etc for v8's and v6's.
Just speak with David Appleby, there an aston martin specialist but have an agreement with VAP.

There may be, but I'm interested in having an OEM tune loaded without tripping any alarms next time it gets serviced. VAP tunes may do this, while pulleys are (potentially...) adding Torque where I don't want it (at lower rpm).
So official V6S or '400' tunes only, loaded such that not only is the car happy under all conditions, but so is the JLR diagnostic system when connected.

I don't want to drag the JVIII engine thread off topic so I thought I'd start a new one. There's lots of discussion around tunes exceeding the basic engine design and or the OEM Jaguar settings so in this case I'm asking about the V6 engine only.
It's agreed I believe that the engines in the V6 Base and V6 "S" are one and the same ? How about the V6 in the new "400" ? If this is also the same but JLR have just found a few extra horses and torqs by changing the software, that would suggest to me they already know what the safety margins are and if so, 400HP wouldn't be at the limit.
Has anybody flashed a V6S OEM file onto the V6 base ? I'm sure the dealer wouldn't do it but those with their own SDD access ? Does doing that cause a Non OEM Calibration flag ? How about the "400" file ?
For those folks who don't desire every single pound of performance from their engine but would be happy with "next level" maybe this would be enough and let them sleep at night ;-)

Frankly I think both the V6 and V8 F type powerplants have proven themselves to be robust at the stock power levels (all of them) and beyond. I certainly wouldn't worry about a VAP tune on a V6 pushing power to a level that the design can't handle....nor would I base any decision on that "other" thread.
2 cents,
