hi there , my previous A3 was a 170 tdi .
I had it remapped , miltek big bore down pipe (dpf delete) dpf delete software remap , miltek non resonated full system , all done by JBS auto designs.
Initially I had the "wild" map , found it very annoying to drive after the novelty wore off, barely touching throttle gave 100% throttle .
Car was never rolling roaded as it was not included in the price ! and when mentioned said the rolling road was out of action.
so no power figures are available for my car.
That said once I had the remap redone by JBS as "mild" I had no other issues , car drove well and certainly had loads of torque.
in fact too much , 6 months after remap the clutch started to slip so that was replaced with a uprated sachs clutch and a standard dual mass flywheel was also fitted .
For a tdi the car was quick and did push you into the back of the seat , had a couple of duals with other cars and thet really didnt pull away that much.
I saw no real improvement in mpg , not that i was looking for that , averaged 45 mpg over 25 mile A road drive to work.
was a little harder on front tyres , too be expected.
car passed 2 mot's in tuned state with no issues , and was remapped at 56k and was sold at 87k .
one other point to note it did belch black smoke (soot) on hard acceleration , so it is obvious the dpf is removed , and depends if you like a dirty rear end , ooh errr !
the dpf delete pipe certainly made the turbo spool up a lot quicker , and you could hear this as well as feel it.
hope that is of some help.
john
