Default Paramount Tune 5.0 N/A Worth It?

Hey guys just picked up a 2014 XK Coupe. Has anybody ran the Paramount tune in there normally aspirated car? If so do you think it was worth it they're claiming 50 horsepower but that's a lot from a tune but I'd like to hear from you guys and see what you think. Thanks

Always nice to have a link:

https://www.paramount-performance.com/xk-2006/

A third of the way down the page at £599 GBP $720USD

Weirdly the same BHP increase they are quoting for the SC 5.0 and RS, so it doesn't seem plausible to have the same figure covering all 3 variants (IMO)

Tuning a stock XKR to get an easy 45 hp is to give it the -S tune.
Easy peasey.

CJ did you check out the URL?

Most know that you can easily get 45+ bhp out of an XKR, the point being that paramount are claiming the same for an XK, which the OP owns, also claiming the same for an RS.

I suspect that you'll never be satisfied with an XK simply because even with a tune it can't come close to the low-end torque provided by a supercharger. My advice is to save your money and enjoy your XK for what it is while you keep shopping for an XKR. I think you'll be a lot happier.

The XK has more than enough power for normal city and highway driving. The XKR is overkill and you can't legally make use of all of its power on the street, even the 4.2L. But it sure is a hell of a lot of fun when you don't get caught!

You asked the same question a week ago about the Paramount tune with no responses. I suspect the same for Eurocharged and Viezu. Why? Cost/benefit analysis. See post #6, above.

Even if owners are out there who had it done, they might be reluctant to admit that they wasted their money.

The bottom line is that it's your car, your money and your choice.

But if I were to do it, I'd want a written, money-back guarantee of minimum objective results as measured by a dynamometer, either as absolute numbers or a percentage. If a tuner doesn't have the before and after data, how can you trust him? How does he even know if his tune works as he claims?

As with everything else in life, Buyer Beware! Know that you can't always get what you want! Thanks, Mick! Now that tune has withstood the test of time!

A guy who used to be on this forum (Mandrake) did a Eurocharge tune with the pulley and intercoolers with pump. He got about 100 hp out of it. Also cost him like $3500 and a whole week of working on it.

Mandrake had a 2010 XKR. HIs experience is irrelevant because the OP, viper1997, has a naturally-aspirated XK. How do you extrapolate XK results from an XKR tune?

Wow, JMS a bit.
Anyway, Mandrake used Eurocharged and was happy with the result. My post IS relevant, but not fully. I COULD have said 'Joe had a Eurocharged on his car, it didn't do anything' and that would ALSO help.
("JMS" means "Jump My ****" in this instance)

I had a ETG tune done on my 2012XK NA vert along with a Mina exhaust and got a significant increase in BHP. Although I didn't have a pre-tune dyno done, I did have an after tune dyno done which showed a significant increase in BHP. Unfortunately I am unable to load the results on to the forum. But, if you want to see the results, pm me with your email address and I will email the results directly to you.

Thanks, Ralph. I stand corrected. Because you spoke up, the benefit must have been worth the cost.

Ralph, whilst.you can't upload the dyno, (not sure why though?) any reason you can't give the headline figures?

I was skeptical on another tune on this forum think it was Ralph's infact , as the power was a quoted at engine (440 or 420hp) and not the wheels

My apologies if it wasn't you Ralph

I'm going to try to upload it again. It worked! So the Dyno printout is there for all to see. Don't forget to compensate for the HP loss through the transmission to the rear wheels. Thee are differing viewpoints on how to calculate the loss. Hence, I leave that up to the reader.

Agreed about the tranny loss, some quote as low as 9% others as high as 15%, so am unsure what to make of your graph, since so few state the tranny loss equation.

I can't see torque figures? Mine had lost horses at 493 (stock 510?) But had 475 kb-ft of torque which is up 15 or so...which was weird!

Ralph , I will break the bad news for you but your numbers were on Dynojet Dyno which reads highers than all other rolling Dyno types since it's not load bearing. The numbers apear as stock HP numbers.
Just as a reference, another forum members stock numbers for his 5.0 na car were at 324RWH on a SuperFlow Autodyn 30 (load bearing Dyno)
