It says:

"The newer Renaults with twin lambdas are not suitable for de-catting, these setups are there to comply with European regulations, there is a lambda before and after the cat. Basically if you remove the cat then the rear lambda gets a reading that its not to happy with thus the car tries to compensate for this result, which leads to crap running except on open loop mode."

Is that true?

the second lamda sensor is there to test the cat it doesnt alter the engine running at all.its the first sensor that moniters actual engine emission output so any changes made by the computer are based on the readings from the first sensor.
