2016 Jaguar F type V6 340hp tune to 400hp?
Hello guys, I spent 5 beautiful years with my F type v6 coupe, since then the car has always been making me smile, from looking at it before getting into it, to starting the engine and enjoying the exhaust note and the more than enough crackles produced at each acceleration. It has come to my attention that the difference between the engine of the f type v6 and the f type v6s is simply a tune that accentuate the power that can be delivered. Is this info right? And is it safe for the car to be tuned to 400hp without any structural changes? Has anyone who tried the tune in a normal v6 experienced any engine overheating or other types of issues ?

VAP
There are a few threads on Velocity AP (VAP) that discuss this thoroughly. A tune on the base 340 gets you around 400 and the tune and lower pulpy 450 if memory serves me right.
Welcome to the rabbit hole of mods though. There’s never just one. I love my base 340 but it’s not a sports car. If you add hp then you reveal the next deficiency. No limited slip diff. Crap stock suspension. And it’s a heavy pig. I’ve had mine on a track and know some of what it can do and have seen its limitations. I personally enjoy mine for the awesome GT that it is and dump money down the performance rabbit hole on a car that is more suited to that kind of work.

Yes it's safe to remap the AJ126 V6 to about 400 hp, which I'd say is its natural safe power output. The base 340 is exactly the same engine and just down tuned to 340 hp. Unlocking its natural performance through a remap is the most straight forward performance mod you can do, provided that you're out of warranty or don't mind voiding an existing warranty.
I had the same engine in an XF before my F-Type. That engine also had 340 hp stock and I ran it remapped to about 415 hp during three years without any issues. There's loads of more info on this topic to search around and you'll find more input.

I also tuned my base 340 to 416 through VAP (Stage 1 ECU tune only). One of the best aftermarket companies I've ever dealt with. The engine can handle that without issue and it makes the car that much more delightful to drive. I'd recommend the tune on the base 340 more so over the 380 or the 400 just because of the bigger percentage gain of HP you get. From a value-to-performance perspective, it can't be beat.

Yes, I agree pulley and tune makes for a very lively car. Apropos (word for the day) BHF's comment, I found that going to forged wider rims and michelin rubber gave enormous ride and handling improvements over stock 19's and P zeros.
I would have a hard time saying whether i get more enjoyment out of the increased power from the VAP pulley and tune or the nicer ride and sharper handling from the new rims and tyres, but if I had to choose one I would say that the wheels would be my pick, it really transforms the car, and it is something that wont impact warranty and can have a visual improvement as well. It costs a fair bit more, but worth every cracker IMO.

I have a '18 base v6 and did the VAP stage 1 tune, as well. It made an incredible difference going from 335 to 416hp. The car definitely feels like it should have had this much power from the factory as it made the heavy feel disappear. I have had no problems. Well worth it!
Just as significant was my recent addition of H&R lowering springs [1.2 inches] which also made a palpable difference in handling due to lowering the center of gravity and the increased spring stiffness. The sensation of body roll is markedly reduced. I also believe the lower stance enhances the car's appearance. Again, well worth the modest cost.

Nice to see that a lot of you guys actually did the remap, I think I might do it too, but I’ll remap the engine from 340hp to 380hp instead of going all the way to 400hp to let a certain margin. Apart of not having an LSD and adaptative suspensions,I think the car will handle the power! I’ll maybe remove the P zeros and get Michelin Sport 4 s though.

Also I have the super performance red brakes on mine so, apart of not having an LSD and adaptative suspensions, I think the car will handle the power! I’ll maybe remove the P zeros and get Michelin Sport 4 s though.
If you had super performance brakes the front and rear discs (rotors) would be pretty much the identical size.

Yes you are right I thought the red calipers were a direct indicator of super performance brakes! Turns out Jaguar gave the red calipers option on standard brakes for the 2016/2017 models. Thank you for the info!

Remember, Jaguar has a 400hp version of this car (400 Sport) with the exact same engine and internals--just a tune--so they clearly designed it to be supported under warranty with that configuration. And since the VAP tune is only 4% more at 416hp, there is no real inherent danger with their default tune. The AJ126 engine can handle quite a bit more.
