please post up when you guys find out a good tune / pipe delete set up.
Has anyone removed the dpf and all the cats with a tune yet? curious about mpg gains
I want some info, i dont care whats legal or not.
I'm thinking about trading my prius for a TDI cup. EXTREMELY interested in this mod.
I have a DPF-less truck and it only soots when you get on it hard, and thats only a bit when you start off. the Tune makes all the difference.
I'm going to get ahold of Edge Tuning, they may be able to crack it with a proper DPF delete.
www.hsperformance.com does both pipes and tuners, they may have some input if there is enough interest. they were the first to remove it from the 6.7 dodge.
There are Huge gains after removal of DPF. Power gain, torque gain and 10-20 mpg. The Cheapest way to do this mod would be removing your PDF of the car. Cutting out a section,removing filter material inside and welding it backup. ECU will also need to be modified/re flashed so ECU No longer requests any regeneration, this is what dramatically improves MPG. If you can read the ECU file yourself i can modify your file to delete DPF so there would be no regeneration and not codes thrown for DPF. PM me if anyone is interested.
Have you tested this on any other CR TDI's? If so, how many & how many miles? What type of increases are you seeing?
Very interested in doing this but want to make sure I'm not losing any reliability.
Its pretty easy to get it out. Its a little tougher than removing a typical donwpipe, but its just some vbands a few bolts, sensors and a fuel line. I am slightly worried about gutting my DPF, simply because I would like to be able to revert back to stock when selling the car, but if something isn't released soon, it will be time to fire up the plasma-cutter
Okay so heres the news I'm sure you didn't want to hear. I got the car up in the air, the amount of metric vbands and other stuff makes me think I should just gut my dpf also. It wouldn't be cost effective for me to do it at this point and get everything milled. Waiting for someone else to come up with a solution. Sorry guys! I might mod mine but at this point it isn't worth it to have one made for me.
Looks like you need to drop the subframe to take it out too. I have a few other things to do before dpf delete if thats the case. Someone make one!

I will pick up the slack, I actually already have the fittings CNCed and am just waiting on a the CNC benders now. Anyone looking for more details can contact me at Kyle@performance-diesel.com
Themachinsy, I know what you are saying on all the flanges and fittings. I started this almost a year ago to find VW has four versions of downpipes! These things also require 6 custom bungs all different sizes and custom vband flanges that are metric. Needless to say, much more work than a 1.8t or 2.0t downpipe and added costs.

Well the good news Is I might be able too! I just sourced some replacement downpipe filters that should work for higher hp ratings in these cars. The costs are a tad high though, but no where near oem replacement costs! Once I finalize getting info from some of the local and foreign sources on engine specifications and requirements I should have a good idea if they will work out or not! So clean diesels will be for racers too!
hooray! MOAR HP and TQ
Something I thought would be kind of cool was replacing the stock pipe with 3in,
keeping all the stock equipment, just cutting the stock pipe off and welding 3in back on.
I wonder if the 3.0 TDI stuff would fit and flow a little more, but still keep the visual inspectors happy.

I can get CUSTOM EURO PLATES
37.89 AVG MPG over the life of the car in Germany!
This is very interesting keep up the good work guys! I would go the hollowing out the DPF way and get it retuned or reflashed but thats cause im a broke guy! Can someone send me a link to show me how to reflash my ecu and get rid of the DPF software? Thanks guys.
