Turning 140bhp to 170bhp

[Curry]

I have had my b7 a4 for 6 months now and love it, great for long journeys which my old car was not very good on being a civic type r. My question is what needs to be done to turn my a4 from 140bhp to 170bhp like they come out factory, is it just mapping or different turbo etc? I have found being auto it lacks power sometimes so a bit more would be helpful.[URL=http://s259.photobucket.com/user/mc_1985/media/DSC_1566.jpg.html][/URL]

I should have said it's a 2 ltr turbo diesel auto.

I'm not sure I think it's mapping try decatting it helping the turbo making it more pokey mines a manual bre new turbo recently pulls when needed any gear any revs

remap + egr and dpf delete should get you to 170(maybe more)

What engine code is it 90% yours will not have a dpf as mine is 57 and doesent

Also oil pump drive is of concern depending on engine code .

A simple remap to 170 / 180 will make it drive better than a stock 170 would anyway.
