I want to tune my 2015 S and I'm looking at the Velocity ECU upper and lower pulleys. What are the disadvantages to tuning? It seems there aren't many failures. Please advise, thanks.

 

We've been tuning these for a long time now and have pushed some 5.0 cars up to 800 hp with no issues on reliability. Also we currently have the fastest F-Type R on dragy boards on 1/4th mi records , car has minimal mods , stock exhaust still.
Reach out for a quote , we carry Anti-gravity light weight batteries, lower , upper pulleys , intakes, TCU and ECU remote tuning done through a phone app on your phone.

 

I’ve had the VAP tune only (no pulleys yet) for a number of years. It doesn’t really produce meaningful HP/torque gains without pulleys on the V6S, but it does smooth out the torque delivery. Never had an issue. I plan to do the lower pulley at some point, but my engine is pinging occasionally, which I think I should sort out before adding more power. (100k miles on it.)

When I eventually add a pulley, they’ll give me a new tune at no additional charge.

 

I have a V6 and buy from VAP. The Phase 1 tune, in addition to the above, pulled stronger at higher RPMs, you can see this on the VAP site dyno testing. I later added the lower pulley and wow a MUCH more muscular power delivery! A lot of fun. I am now awaiting delivery of my ported supercharger and upper pulley, cannot wait!

 

I had a V8S tuned. Only regret was not doing it sooner.

 

Just make sure you're on top of maintenance and have all parts prone to developing issues replaced including coolant pipes, water pump, injectors (if you can) etc and stick to a shorter oil change schedule and you'll be fine.
I'm loving my Viezu tune on my manual V6. No changes to the pulleys.

 

V6S here. Started with the tune, but based on a discussion I had with VAP, they provided one that was "pulley ready." I got an update for a minor driveability issue (the earlier tunes had, then added the pulley later. The driveability issue was that in a narrow range of rpm and throttle position, it was a little more sensitive than ideal.

Long term, there is no reduction in average fuel economy, although driving habits have changed considerably (no more commute), and driving enjoyment is much improved. The fatter midrange is especially appreciated on twisty country roads. For me, there is no reason to add an upper pulley. The marginal benefit is small and I'm not going to go to E85. I have nothing to report on the down side.

Choose a tuner you trust, and get a tune that matches your intended usage.

 

Thanks for the replies

 

I flicked you a PM concerning my experience with a car that's probably the same age, I'm not sure whether I sent it correctly lol

 

@SS4PKWhile I cannot comment on claims made by other companies, I can speak confidently to VelocityAP’s experience and approach. We maintain a high standard of professionalism and deliberately avoid engaging in public debates or commenting on online posts regarding other companies’ products.

VelocityAP has been tuning this platform for over a decade and has served thousands of satisfied customers worldwide, not only within the JLR ecosystem, but across a broad range of vehicle platforms.

We consistently encourage customers to choose a tuning provider they can trust, one that stands behind its products with proven experience, a strong track record, and comprehensive customer support, this avoids any sort of problems in the future.

Our tuning solutions are engineered to be safe, reliable, and fully data-driven. We utilize a proprietary data-logging system developed in-house that captures information unavailable through conventional logging tools. This allows us to analyze critical parameters in greater depth and build calibrations that prioritize and maximize performance, consistency, and long-term durability. In addition, VelocityAP operates a fully equipped in-house dyno, race shop, and full-service facility based in Canada.

Extensive testing and R&D are conducted on our own vehicles to identify limitations and address potential issues before our products reach customers. When concerns do arise, they are most often related to improper installation, inadequate maintenance, or undisclosed third-party components that prevent accurate calibration. Customers should also be aware that performance modifications may result in increased service intervals for certain components, such as oil, belts, differentials, and transfer cases.

Warranty considerations are understandably a concern for many customers; however, any vehicle modification carries inherent risk. That said, it is highly unlikely that our tuning solutions would cause catastrophic engine failure unless a pre-existing condition was already present. This confidence is rooted in our calibration philosophy and the quality and safety standards applied to both our software and hardware offerings.

If you have any questions or would like to discuss your specific application in more detail, please do not hesitate to contact us.

 

Owned my R for years and cannot believe I have not got the tune and pully and yet cannot use the OEM power, so not sure the point to adding it. It will most likely reduce your resale worse than it already will be with doing a tune.

 

I’m similarly to you in that I cannot imagine needing more power on the street than what a stock R has. That said, I respect the choice other car enthusiasts might make to tweak their ride. Some people don’t worry about resale, and they focus on maximizing their enjoyment of their car. For some this means tuning and modifying, which is completely fine.

Also, some of these guys have other goals beyond the street…Track work, drag strips, etc…Lots of variables that drive the different decisions people make…

Cheers

 

The question was asked by a V6S owner. Your R has more power than the V6 does with both pulleys and a tune, so it's not quite apples to apples.

 

Resale? Why would I ever sell my F-Type?

 

Exactly. I literally plan to have this car out last me, especially given the current direction of cars. This was one of the reasons I purchased new. Resale doesn’t even register with me. AT ALL, which probably makes me a bit of an odd ball ;-0

Maybe the car landscape will revert and go back to a time having new cars that are interesting, but I highly doubt it.

 

Doesn't make you an oddball, just a different class of car owner. There are plenty of Jag owners, of F-Types and others, that want a pretty luxury car with plenty of power and good handling for a spirited weekend drive. Nothing at all wrong with that point of view either, and nothing wrong with caring about resale either. Just not my particular point of view. I fully intend my do be driven until its death -- and I suspect the death will not be a natural one. It will be well maintained, but it is being modified and tuned. It's being turned into a GT race car -- specifically for open road racing. It will be kept as normally driveable car as long as practical, but with the interior starts to deteriorate too much, that too will start to get modified. If I were to sell it, for some reason, the target audience would be a like minded owner, who has a different view of what has positive and negative impact on resale value.

So... to those that want -- tune away. Those that don't, that's fine too. Just drive your damn car and enjoy it as its part of a rapidly dying bread.

 

Welcome to the world of "needs" versus "wants".

 

Yeah, when it comes to car enthusiasts, no truer words have ever been spoken. Things making sense need not necessarily always apply ;-o

 

Not the kind of tune we had in mind, but at least ya tried to put it in a thread that made some sense I guess? ;-0

 

I have 3 Jags XKR, XJ SC 5.0, F-Type R
All AlphaJag tuned perfectly every day street drivable yet with lots record setting times one them, wouldn't have it any other way 😆
Don't forget proper running can actually make changes in reliability in the positive direction. Stock programming is far from perfect and many things in OEM can be improved. Take the Eco start stop, it's far from good for your engine in fact it actually hurts your catalytic converters, your 02 sensors and frequent start stops cycles aren't the best for engine reliability. We can easily disable this in tuning and highly recommend this ,just one example..
