Caddy 2.0 BKD with a 52mm hybrid turbo

dynoed 150 on stock fuelling on hybrid turbo finished at 209bhp / 350lbft, full boost at 2500 and very snappy on the road.

It may be weird to appreciate it but we'll forgive you.

I randomly came across a post from a competitor, and my interest was drawn to a phrase within it which was quite bold along the lines of 'if you want to have your daily driver diesel dyno tuned, you're probably a bit of a weirdo'

I thought that was a bit bold. I think, looking at the wider context that they were suggesting the 'road is where the power is at'. I think the argument is basically a dyno isn't all that.

I have no quarrel with competitors but I do kind of have to be the devils advocate with a few, what I hope are common sense views:

- a dyno gives me data in a safe environment, before we put it on the road. It means a lot to me does that. It's nice to be able to watch the data and back off on a dyno then you know, focus, steer, navigate traffic and watch the graph on a laptop.

- a dyno provides a consistent test environment to test changes, unlike having to find a different hill or whatever. It means a lot to the integrity of our work and data. Again means a lot.

- a dyno gives me assurance of what I am doing is having the desired effect

- a dyno gives you assurance of what I am doing is having the desired effect.

So with the above in mind, I dyno every car i can that will run on our 2WD dyno. It's much for my benefit as yours - seeing the numbers helps me gauge things not just for you.

I'm not as biased as one would think either, when I started I didn't have a dyno and I managed. Doesn't mean I'd go back.

But I don't think you're weird for wanting a graph :) You really aren't. Unless you are, in which case its your secret.

What if I told you I deliberately capped the gains on this?

This is a Transporter 2.0 CR with no mods at all, running safely with over twice it's stock power.

Those well versed will recognise it to be the 84bhp variant, which is limited from factory with software upgrades able to bring it up to the higher power factory models, and to add a cherry to the cake - it can then be 'stage 1'd on top.

Torque has been flattened to protect the springs on the flywheel as it's likely to be loaded.

Start:
83bhp
169lb/ft

Finish:
173bhp (plus 108%)
290lb/t (plus 71%)

There's really no way you can say a stage 1 going from 115 to 181bhp is bad news (over 50% uplift) :)This was a stage 1 ...

There's really no way you can say a stage 1 going from 115 to 181bhp is bad news (over 50% uplift) :)

This was a stage 1 on a Ford transit 2.2tdci with Siemens SID208 management, these tune up really really fantastically (once the speed limiter is gone).

Afternoon

We are having some phone issues, so I would recommend anyone trying to reach out to us to do so my our contact form on our website (DieselPowered.co.uk), message us here, text message.

We will obviously try and respond as normal but as phone calls aren't registering we have no idea if you've tried or not.

Should be sorted soon :)

Evening (or good morning) all

Just a quick one - this advice makes me quite unpopular but it's based on experience, time and time again.

If you fit a larger turbocharger, or a hybrid turbocharger or even jsit have a recon one, and the car doesn't drive right, in 90% of cases it's because something isn't right. It's almost certainly NOT because the turbo needs mapping in.

This might seem contradictory as it's said by everyone (and in some contexts even by my) that larger turbos needing 'mapping' when fitted, but the two opinions are actually complimentary when you think about it in full context. A larger turbo needs mapping in to get the best out of, it shouldn't need mapping to 'work'

So the determination is simple - if it feels that its a bit laggier but very much like the old turbo in power, you're probably good. If you're thinking somethings wrong I can't get any boost - you've probably got a genuine problem.

Almost every modern diesel ecu will use closed loop control and put in a reasonable effort to produce boost no matter what turbo is bolted on, and beleive it or not, for most setups the tweaks we make to turbo control should be quite minor.

So if you put on a new turbo and it can't make any boost cuts - there's a very real chance it can't be mapped either.

I'm raising this as we recently had an enquiry and from the description it immediatley made me think 'somethings not right'. I'm not sure if my caution about something being wrong and the fact I focused on doing diagnostics rather than mapping put the customer off, but I'd bet my bottom dollar that thats where the time needs to be spent.

Use this as a bit of good faith advice :) if it seems broke its likely broke and a bigger turbo should at least try to act like the one before it, even if its a touch laggier.

That said, we're not quite done for 2025 yet, but we would like to wish you all a fantastic period 😀
