EGRand cooler delete = no more carbon buildup. Buzzken 2.5" downpipe /w used ebay GTI muffler. Downpipe bigger is not better, its what you use most of the time..velocity. Stage 2-3 Tune /w dynamic idle. Once EGR is deleted, the EGR cooler can be removed. Best time to do this is during the CR170 swap.
The2009+ Jetta, Golf diesel, and Audi A3 TDI have a more complicated EGR system. The low pressure EGR gasses are filtered before being sent through the cooler and back into the intake. The high pressure gasses go straight from the exhaust manifold to the EGR valve and into the intake.
The1Z uses an ECU which knows when the EGR is working/not working when triggered by seeing the MAF value. So I don't think it would work, However there are enough chipped ECU kits out there which just delete EGR function completely- one way to make a TDI make more power and better economy
Addingan EGR Delete to your Engine has many benefits, it allows cleaner AIR into the intake allowing for higher performance and better mpg, it also will remove the intake of harmful carbon deposits that build up over time causing A loss of performance.
