Hello,
My S3 is currently Revo stage 2 with a Revo CAI and stock exhaust but the downpipe is modified with the pre-cat material removed.
I'm getting a BCS downpipe with de-cat fitted on Wednesday, I'm not expecting an EML to come on as I've already got stage 2 software.
I've been informed that running a de-cat will cause it to run lean without an update despite having stage 2 software.
Can anyone elaborate on this for me please?
If so, would this have to be a Revo map update (so only a Revo dealer can change) or can any garage update the necessary parameters on the ECU?
I'll be calling R-Tech this week to get booked in for stage 2+ but that won't be until late March/early April, so would running lean due to a de-cat for over two months have a detrimental effect? I know that running too lean can cause damage but I'm not sure how lean (if any) a de-cat would cause, my guess is it's only marginal so I'd be ok to leave as it is until the new remap.
Cheers.
