Running rich

[Wellbs]

Car is decatted, rs tuned but has slight blow from the silencer could this be causing the car to smell like it's running too lean? (No fault lights ect)

It will smell lean because its decatted

That's what I thought tbh, is it likely to cause any damage?

The only reason I can guess a car is de-catted is from that lovely smell 😌
No there wont be any damage, its just purely because the cat is removed and not there to filter emissions which is its job.

If the fuel trims go too far out of whack it should light up the engine warning light. If you still have the RStuner you can check the long term fuel trims and see if the car is trying to compensate for lean running by adding more fuel.
