guys looking to get this done http://www.revotechnik.com/product-details/software/audi/a4-b8/49/stage-2 what would be the issues with Mot and car reliability would be OK? I know it depends on other factors but how many have gone down this route having dpf delete and experienced any issues or best sticking with a stage 1?
A DPF delete or stage2 is an MOT fail if the MOT tester can see you have removed the CAT or DPF, if you have the guts removed and get the CAT/DPF welded on the top where he can not see it will pass. A good stage 1 tune/remap will give better emissions but a good stage 2 is not emission friendly.
Stage 2 won't make a difference, doesn't go on emissions and goes on soot content, a decent map and it won't throw much out
