It's not your plugs. If you did 7 pulls on the dyno then you are most likely hitting catalyst over-temp protection mode and the car is either dumping fuel, or pulling timing to get the EGT's down.
These cars are extremely sensitive to cat temps, even 2 pulls in consecutive order without adequate time in between will tip them into protection mode. You need a lot of airflow (I don't see a big fan there, but I'm sure you have something set up there?) and if you can get a couple of fans pointed at the cats as well that will help.
Interestingly, having seen a few 'VMax' tunes from people who switched over to our stuff, one of the most concerning things was the fact that some of the protection mode maps had been edited to lean out the AFR. My guess is that the tuner was running the car on the dyno and seeing rich mixtures and editing the tables thinking they were the optimum fuel strategy, when in fact the car was just too hot and they were editing the safe mode tables.
We are well into the 100's of tunes for these and the V6 engines, multiple dyno sessions and I've yet to see a set of plugs go bad as a result. I would monitor your cat temps and allow more time between runs, before you go changing them.

What are your thoughts about the power dip at 5800-6100rpm? It dips then it climbs up quick.
Appreciate your response.

Besides, I'm doing someone else a big favor
Spark plugs going bad after 1700 miles sounds implausible to the point of unbelievable.

You didn't ask me, but on my V6S, the OEM power climbed to 6000 rpm, fell to 6500 and then headed north again to 6800. I believe all of our cars hit peak hp at around 6000 rpm until they are tuned.

ETG (ecu tuning group)
Just curious guys.... Has anyone ever gotten a ecu tune from ETG (ecu tuning group)? The owner's name is Jags. I did a tune by him a few months ago (on my '14 BMW 650i Gran Coupe). Anyway, he tells me he can get my F-type R to 637 HP with tune and a pulley change. What do u guys think?

Don't know what you mean by this..I have a similar rope that was on the rear of the car on the front when they were doing the dyno.
Lang Racing Development together with GSR did the Dyno..they do a lot of Exotic and High End Cars.
So they know their stuff.

Okay, so they did not have to remove the front driveshaft from your vehicle to do the testing? Some dynos (including front and rear roller mustang dynos) do not have the front and rear rollers physically linked together, which would cause damage on the F-types AWD system. I saw your car on the hoist and thought they might be removing the driveshaft.

We did a dyno again on Tuesday but the stock reading is still not good. I have a schedule with Jaguar Service to have it checked since the car feels like its misfiring at 5,600rpm.
Once this is resolved then we can move forward with the tune again.
