The most powerful production 2.0 TDI (CUAA) - REMAPPED!

[@mwh2412]

This is a great engine, intake pressure drop is really impressive. Lots of back pressure from the SCR system and back boxes though - lots of potential to drop the EGT with an exhaust!. If you ran the engine on a slower curve on your dyno you'd find the egt's even stock hit 830! BMW B47 25d engines had 2500bar in 2015 also! But only got to 230hp (in the X3/5 etc) and used a CP4.1 - for big power makes it more of a pain as retrofitting of a rail and cp4.2 required! BMW also had twin VNT where I think the passat was only single VNT.

[@DarksideDevelopments]

Its a shame the arms race is over with TDi's!

[@mwh2412]

Darkside Developments - yeah the only arms race left isn’t going to create higher specific power diesel engines that’s for sure!

[@FPVForLife]

​@Darkside Developments Yeah, look up how much NOX is now allowed to get out of the exhaust per km. And then look up how much NOX is allowed in work spaces like offices, workshops, or even restaurants and such. And then you ask yourself how in the f can they justify such emissions standards?!?!?! Oh I just remembered, a german court just ruled the "Thermofenster" as illegal. I don't know the english term for it. Pure insanity and the end of cars.

I’ve been looking for an English language video of a tune on this engine - specifically I have the Kodiaq RS, BiTdi - I assume this is the exact same engine. Having the extended 7yr manufacturers warranty the inner turmoil on tune or not is high! One question I have is that from standstill this engine / gearbox seems to have a lag off the mark, that moment you want to get on to a roundabout in a break if traffic. Even in sport it’s just significant enough to be annoying. I think it’s the time delay element on the throttle map for emissions reasons but I’m not sure. Right or wrong I added a pedal box and it’s solved the issue to a degree. Would a remap sort it out properly? Do you agree there is an inherent lag from stock?

[@DarksideDevelopments]

It's the gearbox, they don't know if 1st or 2nd gear should be selected so they hesitate. You could try a Gearbox tune alone if Warranty is a concern.
