Although car enthusiasts commonly believe that any modifications will void a warranty, the truth is a little less straightforward. In fact, a modification won’t void a warranty unless an automaker or a dealer can prove that an aftermarket part caused the need for repairs. In other words, your warranty will still be valid when your radiator springs a leak, even if you’ve added an aftermarket exhaust.
Dyno sheets generally aren't worth the paper they are printed on. Especially in North America where the numbers are often grossly inflated to the point of being ridiculous.
In saying that, here's a dyno sheet that you should pay attention to.
It's a dead stock 2014 F-Type V8S, two runs, one with a RaceChip, one with it turned off. The HP is at the rear wheels, in the real world, not the usual fantasy numbers thrown around on the internet.
You can see the RaceChip did something, but nowhere near the numbers they claimed it would. Results will be different with an R (we also tested this) but with a V8S forget it.
In the meantime the RaceChip went in the bin, and the car got a proper tune (no pulley, just tune), it hasn't been back on a dyno, but was taken to a drag strip, see here https://www.jaguarforums.com/forum/f...-76mph-219870/
The trap speed is a real world indication of where it's at for power now. 126.7mph tuned vs 118.9mph stock.
So @RacerX I'd love to see what your "662 BHP" does at the track...
Appreciate the advice from all concerned and surely did not intend to create a spirited tug a war on tuning vs. warranty legalities. My previous experiences with modding was normally limited to exhaust and intake which never created a warranty issue. It may be in my best interest to hold off on the VAP tune until next year and be content with the current more than ample stock horsepower. Thanks everyone, your combined knowledge on all things Jaguar is impressive and very helpful to a new F-Type owner.

Like I said, I put zero faith in a 15.6% addition to WHP. Racechip + pulley on my V8 S produces 559 WHP.
There is no drivetrain hardware difference between a V8 S and V8 R.
Not to bash VAP, its a good tune, but your Racechip tune-only (no pulley) dyno looks a lot like theirs on the bottom left. Here is an exactly to-scale comparison on different dynos, obviously.
The green dots show an area immediately pointed out by a very experienced dyno operator of an overheat timing pull that needed to be solved before more power could/should be made. Looks like you have it too. 40 SAE oil solved it for me (right side upper runs).
My best track time is Dragy timed at 3.45/60 11.27/124.0. It's hampered by RWD on 4Ss which might as well be rollerskates. OTOH RWD is 5% lighter with maybe 5% less drivetrain loss.

Last comments, from me, on this subject Jim.
1) We can talk about this, in person, when we return.
2) There’s risk in every single thing in life. Whether it’s crossing the street, adding bacon to your breakfast, or adding a tune. (There’s even risk in not putting a quarter in a parking meter.) Based on everything I know, plus personal experience, the odds of [something going wrong after] adding a VAP tune appear to be extremely low. Naturally, there are few guarantees in life.
3) As a professional commodity broker, all I try to do is look it any market and assess the risk and the reward. And I never ever have “analysis paralysis.”
4) Last but not least—and in keeping with #3 and something I believe hinders far too many people in life, never mind about getting a tune (or having bacon with your breakfast)—don’t overthink things.

So you're saying that your stock V8S made 487rhwp?
But my point wasn't an absolute number, but relative to baseline your Racechip-only tune is showing a bigger relative gain than VAP-only (bottom left, above). As does mine, upper left. That is VAP's own dyno result.
And there I was seriously considering his views/opinions/advice on oil weights for the F-Type.
Reckon I'll just stick with the 17 litres of 5W-20 I have in the shed!
In my base 2018 what do you think would be the relative increase in low end acceleration, say 0-30, 0-60, of the RaceChip offerings? I'm just looking for a bit more on initial launch, like being able to break the rear tires loose and gain a bit up to about 60 MPH.

I knew something was up with this guy. Encountered his asinine posts on this thread and a few others.
I figured this guy was a troll!
Thankgod for that racerx was doing my head in, every time someone mentioned a tune he jump on it with racechip this racechip that, oil this oil that
and then start slagging vap and anyone else who had an opinion about tuning.
I swear him and ambrosia rice pudding must be related

I knew he wasn't the real Racer X. Speed's older brother Rex wasn't like that.
