Has anyone here had any experience with this tuner! It appears as if they are the only one who can really make some more power out of the P400 engine.


I was just trying to see if it was as good as advertised or a viable option. Is there anything else people
are doing to get more power from the P400 engine?

Thanks!

 

I just found this post from a while back…
Tuning Options for Defender

has anyone used any of these on their P400?

 

Hi there, I would be careful with this, not that I remapped my P400 but I have had an engine failure, cyclinder 1 was leaking pressure into the crank case and I am currently fighting with JLR for a warranty engine replacement. The only modification I made was with a Kahn Automotive exhaust.

 

this makes me sad to hear.

that being said, how do you like the Kahn Exhaust?

 

I know but with the correct pressure I am certain JLR will cover the warranty. The Kahn exhaust not only increased power but also sounds amazing especially when slowing down when approaching traffic lights for example, a nice bit of crackle and pop!

 

How was the drone when driving/cruising on the highway?

 

Everyone is entitled to their own opinion, but I would not want my Defender to have that ‘crackle and pop’ when slowing down noise. There are enough of those little toy cars with the cheap aftermarket muffler that you can hear blocks away as they rev their engines every three seconds. I don’t know, maybe they think the ‘chicks’ dig that stuff. Not suited for the Defender, thank you.

 

That particular aspect wouldn’t bother me too much. It’s more the drone that would/could be present when driving or traveling.

But if it adds performance and drivability, that would be really nice.

 

I will likely upgrade mine once the warranty expires. How much is the thing. Do they offer a sportier tranny tune? Thats probably achievable with dynamic mode

 

I reached out to Manhart and they said they don’t have anyone in the U.S. who can do their tuning. So
that sucks… 👎
