Hi Beeblebrox,
OMG have done my Audi A5 about 5 motnhs ago. DPF removal, power remap and a full stainless steel exhaust. All in all- I'm properly chuffed. Choose them after making a lot of phone calls and reading on the internet, on the phone they sounded like they really know their stuff plus the price was about average what I've been quoted.
As for the job- good service, Dave form OMG expalined everything they will do to my car and I was allowed to watch the whole process
, clean garage etc., but most of all- the way the car drives and sounds now! The power is now between 260-270 BHP, so it is SERIOUSLY quick. As for the DPF removal- I went for the full option: DPF deactived, as well as sensors in the exhaust (temperature I think?) and EGR valve, so basically they removed the whole thing- and after the job showed me this on their diagnostic tablet. Outcome- MPG is better by 5-10%, unless I go mental with the gas pedal
, and most of all- my car doesn't tell me to drive on the motorway when I don't want to
Since then I've done about 5k miles, had it serviced by Audi- obviously they noticed changed exhaust, bo no other problems. So far- really good (maybe too good, as I simply forgot about them- and after the job I promised some good reviews if it works ok).
Green light from me!
