Chip optimization td5 recommended

I got my Def 110 2002 td5 ecu optimized by Stockholm Chip Optimering. It cost 300 £ and in combination with blanking the egr it has become a new engine!!
Fuel down from 11 l / 100 km to 9.5 l / 10km. ( 30 mpg?ish) Nominal effect and torque 155hp 400 Nm.!! One can go on fifth gear in steep highway hills where I had to shift down to 4th gear before. In terrain and low gear one can go on idling over ditches really sneaking on low rev through forest tracks like a ghost.
If you are in doubt to optimize your ecu, don't, just do it! It is obvious original software doesn't make justice to the great td5 engine.

put a larger(performance) intercooler too... and then will be 100% perfect...you'll gain at least 10% more power...and protect the engine better

And a full bore exhaust so the turbo spins up faster. Diesels dont like or need back pressure like a petrol engine. Ideally you should run with an open pipe straight off the turbo exhaust outlet but apparently its anti social and somewhat illegal?

TD5 straight through exhaust. 5 alive, as well as tuner mentioned, craddocks, paddocks , also a larger intercooler is needed to get what you want

Got mine from gary at TD5Alive tuning. Full stainless and very good quality. Sold my old stock stainless exhaust and got 2/3 of the cost for the new one back.

good point...is it more noisy inside the car now?...and what about the improvement? ...do you have better throttle response or something?

No noticable change in cabin noise. Sounds a bit throatier outside but nothing to upset anyone including MOT man. Throttle response is crisp with very little turbo lag. I did fit the exhaust at same time as intercooler and remap so have no direct comparison before and after.

thanks for the info... i'm thinking to go for it

I've not regretted it. It sounds good when I'm towing and the engine is having to work for its keep. Not quite as good as a V8 but has that strange 5 pot burble.

I did the exhaust before the intercooler / remap. The exhaust makes the turbo lag absolutely minimal, the larger intercooler increases the lag slightly. I have a boost box, but haven't taken the boost higher, it's at 1.2 now. I believe that taking it up to 1.4 would reduce the turbo lag again...

A VNT would reduce the lag too, but you're looking at a lot of money then

what about just removing central exhaust box and weld in pipe ?

That's essentially what they are talking about. It's a straight through pipe that bolts in place of the silencer. weld in pipe... same difference, except you can't unbolt it.

I have the pipe, just need to get off my bumm and install it.

I did up the boot to 1.4. Really really glad I did

Just keep an eye on your exhaust gas temperatures. They can get hot enough to burn the valve seats if you overdo things. At 1.4 bar you should be OK though.
