Title: Will I be Lean?
Post by: michal marzec on March 09, 2004, 06:18:02 PM
Hiya all,

Just wanted to double check:

Can I get away with Full De-Cat system on standard ECU IF I left the original back box on?

Car is 100% standard apart from that.


                          Thanx Michal

Odds are you would be lean, as always the only sure way to find out is to get it checked.  Personally I wouldn\'t take out a cat without an appropriate ECU in place.

When I did this I was ok, but thats not to say that yours will be ok, best to get it checked at a rolling road station.
