Struggles with motorway speed.

[Roodedoo]

I did all the filters and oil - but not the fuel filter.......

What tyres are you running and how much weight? You haven’t got a massive box strapped to the roof by any chance?!

 

[Bargy62]

Being ex RAC could it not be restricted I know you said new engine but the restiction would be programmed in not a pysical thing so the new engine would be resticted as well

haha, yeah, I do have a big square peli box on the roof which I'm yet to make a fairing for

I had some deletes done and I'm pretty sure any limiter would have been removed too.
It's more that it's working hard than limited

heavy. I weighed one yesterday and it was 32 or 35 kg, I forget

worth checking could be a cheap fix

 

[Roodedoo]

The van is insulated etc, everything but the furniture

do you know if VCDS would tell me?

 

[Roodedoo]

But also it could be the heavy wheels and box on the roof.
Plan is to make a fairing with the maxtrax

 

[Roodedoo]

I guess I need to research testing injectors and pumps too.
Now I know they go faster, there's stuff to do.
Like make that fairing.
And consider lighter alloys

 

[Roodedoo]

I didn't change the fuel filter yet either. So that could be restricting flow

 

[Bargy62]

Sorry but I've never used but there must be others kn here that have had the same problem

Definitely worth doing dirty fuel filters can case so many problems I'd do that before anything else

 

[Roodedoo]

What was remapped - Just the engine or the engine and DSG
What weight are you carrying
What other mods that may make a difference (you mention heavier wheels)

Just the engine, not the box.
Heavy AT steel wheels AT3 225/65/17
Box on the roof, need to make fairing.
Just fridge and battery and floor ceiling deadening insulation etc mid-conversion
EGR delete before remap

DPF getting clogged?

Does it Regen often?

 

[Roodedoo]

Ensuring the entire vehicle is freshly serviced and everything operating optimally. Only a loon would chuck the keys at a remapper without first ensuring everything is A1 first, and a good tuner will be asking to ensure that was the case before they start work.

I guess that makes me a loon
I serviced it and it seemed fine - but I had nothing to compare it to.
It felt a little underpowered, so I got it mapped, and it went faster.
It's quick off the mark, no smoke or rattles.
Just this top-speed issue.

was this service the one without doing the fuel filter

Definitely not the Dpf.
Although it could be worth looking to see if there are any bits of it left in there..

exactly.
I'll do the fuel filter today and see if that makes any difference
