Hi all,
Im new here and was after a bit of advice/help!! I have a 03 reg 136bhp diesel and have been having a few problems with it lately. First is the lack of power compared to whenI first got the car, also there is a judder at 80mph. Has anyonehad such problems, if so what was the cause?

Thanx all.

 

I ahave the 03 6 but is is NOT a diesel and is stock at 160bhp. No such problems yet
Oh Iam at 60,000 miles

 

Hi There
I was wondering if anyone was able to help me with a problem I have. I have a Mazda 6 2002 model (2.0L) and I recently replaced the rear muffler, and would like to take out the CAT converter. But ever since I replaced the rear muffler I've noticed a drop in performance, and I am pretty sure that takling out the CAT is going to worsen it. I believe that I need a piggyback unit for the ECU and to get it re-tuned, but this is a very expensive process. Does anyone know of a DIY piggyback unit that works, or might be able to suggest something else???

Many Thanks
