Have been speaking to several of my friends who had varying diesel cars. A couple of them have recently had their DPF filters removed and remapped.
They have seen some massive improvements in power and torque gains! For example Seat Leon TDI - 170ps, now 233ps!
Could similar performance gain be achieved by doing something similar with the DPF on the 1.6tdci (obviously we're not talking figures in the region of above!).
I've already got a noticable difference by installing a s/s indiction kit and a force air ram kit to the air box enclosure (instead of using ambient engine air, that the highly restrictive oem filter/air box uses).
Any comments welcome!
