Hello all, have just joined and love my 2011 D22. She has a 2 inch lift, winch, ARB bullbar, had canopy, 32' mud terrains, 3 inch exhaust and host of other items. Will upload some photos soon
Blocking the EGR is a quick and easy mod which will reduce the amount of soot recirculating in your engine, no good at all! Just a quick install of a blanking plate, and you can install a oil catch can at the same time too to reduce the oil vapour going to your turbo.
EGR is explained pretty well here: https://chiptuning.com.au/egr_blanking_info/
Have you got a tune yet? Couple with the 3" exhaust you have, it'll make for a totally different drive!
