best tdi mods

well not till after a remap surely?

OP asked for best mods, surely a less restrictive exhaust will help in the long run if going BT/uprated injectors?

That's assuming no price limit of course.

eventually I may go big turbo and uprated injectors ect ect but engine will probably need a rebuild before that its on 134k now

GTX1756VK is your friend

Best mod for a diesel?

Remap and an egr delete in conjunction with a good service and decent quality fuel.

The manifolds on the 130 and 150 are the same.

Just wondering Why is the EGR DELETE so important what does it improve?

They're just **** mate. Nasty recycled fumes being forced back into the engine, mixing with oily breather gases then clogging everything up and causing performance and economy loss.

Delete pipe, manifold clean, oil catch tank, remap - done!

Keep the egr in place and just disconnect it/disable it, it's always good to keep the asv and it's on the same part as the egr. You can fit the PD130/150 egr with the manifold, it doesn't really cause any restriction and there's no power gains to be made by completely removing it but the asv is very useful in the event of the turbo blowing and the engine running away burning all the oil out the crankcase till it seizes solid.

Couple of places claimed 6 BHP gains with their "race pipe" fitted on the 130 engine but I'm yet to see anyone else make this claim or any concrete proof.

The later engine with an electronic shudder valve has the benefit of being able to remove the egr, cooler and a whole host of untidy pipe work in the process whilst leaving the valve intact and fully operational.

Yeh I noticed that on the newer ones, handy.

As for 6hp, do you think anyone would actually notice it even if it was true?
