🚐 Another VW T4 1.9TD – one we absolutely love tuning!
Some people aren’t fans of these old 1.9TDs, but I think when they’re set up and tuned correctly, they’re a cracking van. 👌
Especially with the 5th gear mod as well!
This one came in feeling underpowered, and the dyno confirmed it.
From stock, we’d normally expect around 65–68 bhp, but this one managed just:
❌ 61 bhp & 123 Nm
It looks like someone had been having a play before us… unfortunately, they’d turned things the wrong way. 😬
So we got everything set up properly – correct idle, fuelling dialled in and no smoke.
The final result:
✅ 85 bhp & 174 Nm
That’s a massive 39.3% increase in power and 41.5% increase in torque over how it arrived. 💪
No silly smoke. No bodges. Just a properly set-up and tuned T4 that now drives like it should.
There’s plenty of life in these old 1.9TDs yet! 😎
