I’m looking for a reputable tuner for my 2015.5 RRS 5.0L SC. Primarily for a bit more power but also to adjust the extremely laggy throttle response.

Who has tuned their RRS? Any issues with the dealer? I still have warranty for a few years, so dealer detection is a huge factor for me. What are your overall thoughts? Worth it? Any issues?

I’m also new to the RR world, so who is the tuning guru for the L494/L405 platforms? I found a few places mentioned in the forums, but i haven’t been able to reach 3 places I've attempted to contact (won’t name names), but that right there doesn’t give me the warm & fuzzy. If they won’t get back to me when I'm trying to give them my money, they surely won’t respond if there is ever an issue.

Stuart over at Velocity has been great. I used them for my tune on my v6 and will be using them for my tune on my new v8

http://www.velocityap.com/product-p/vel-rangerover5.0ecu.htm

This will put you at 605bhp and increase throttle response.

Best part is they send you the tuner so when a dealer visit is needed. Simply flash back to stock.

Also went w/ Velocity for my V8..... got the ECU tune and crank pulley. You won't regret the extra power and respond.

Did you install the pulley yourself or did you have a shop do it for you?

And as for the ECU bit, is it possible to just set it back to original with that same unit?

I've been thinking about tuning also, but it's already pretty quick in dynamic sport mode. Not really sure how much faster I need it. I have been waiting for one of the occasional holiday sales to pull the trigger. I am leaning towards the velocity tune.

I smell a group buy ... ?

I wonder how many units we'd need for Velocity to give us a 20% break ;) hint hint , nudge nudge.

I'm in the same boat. I really don't feel like it needs more power, but I also will not ever be happy with how much I have. I know that.

I also have the Velocity ECU tune and am very happy with it. They were great to work with, very helpful with the installation process as the unit glitched. Yes you can just reflash back to stock with the same unit if needed. I also have the supercharger pulley but haven't installed yet- plan to do it myself in the next couple of weeks. Process is described elsewhere here.

Now we’re talking! I’d be interested.

Hopefully Stuart will read this soon and chime in.

Think I would be tricked into a group buy if it is an option for my ‘18 AB. Coming from a X6M, I am struggling with some lag.

Can you guys with Velocity tunes comment on changes in drivability? I feel like my car is very jerky in Dynamic mode with transmission in S (stock car). I came from an E92 M3 which has a very linear pedal feel which I really liked. I'd like more power but if the tune amplifies this issue, I would be turned off.

Also, how noticeable is the power increase? No disrespect to the team at Velocity AP, they seem well liked by those have purchased their tune. However, I still have not seen a before/after dyno reading of a RRS Supercharged with their tune. I know they exist for the same engine in the Ftype R etc. but none on this platform. Another vendor with a V8 tune was accused of exaggerating their power claims on this forum. It couldn't be hard to do themselves or offer to reimburse a customer the cost if they did it and posted the results here.

That's probably because you can't dyno AWD cars with traditional equipment. I have yet to find a shop that does it locally.

Had my 2016 tune and pulley done through ECU about 2 years ago. I would do it again. The additional power for the cost is a no brainer. Saves you $30 K buying the SVR (at least as the power goes). Have had my car back to the dealer numerous times for general service calls, had some updates done and couple of small problems and never an issue. Don't have to change it back and forth for the dealer. They can't tell. It's not like it changes the car where it's really noticable to a service tech just driving it around to test the breaks or a noise. And they certyainly are not looking for it. But with daily driving and hitting those high speeds you can feel the difference. Car is pretty powerful on it's own and I don't really need the extra, but I would definitely miss it if it was taken away now.

I agree the 30k premium is a little high for SVR, but it's really not about power for most buyers. The exhaust, the body kit, and the seats did it for me. The power difference between my SVR and my SC Dynamic is almost unnoticeable. Although I will say it does shift a hell of a lot quicker with the paddle shifters. It's feels just as quick as the 458 ( I know that sounds ridiculous, but its as fast as it makes no difference ). Anyway, more power is obviously what we all wanted when we went for the 5.0L V8 SC. I'm glad to hear it hasn't interfered with service at all.

One more question I have is regarding the pulley. It looks like you have to grind/sand down the pulley shaft quite a bit to get the new pulley in there. Does that mean the oem pulley can no longer be used after the mod?

While I agree that’s the reason, I think that the extra effort should be made. We are spending over +$1,500 per car for these tunes, so hunting down a time slot at an AWD dyno is certainly warranted IMO.

I watch Subaru, Evo, Lambo, GTR dynos daily, so tuners can ring up any of those places and lock down some dyno time.

I would feel much better seeing the HP, TQ and AFR results.

I have to disagree with this. Not sure where you are in Cali but I'm in a Canadian city of just over a million and there are at least 4 AWD dyno's here. Anywhere with an upscale car scene should have one.

I just made an appointment at a local shop to do the baseline Dyno next Thursday at 9am. I'll also test with and without K&N filters to answer that question at the same time. Will post videos of everything if I can.
