Hi everyone,
I've been logging my car lately and noticing pretty consistent knock retard and some ignition retard. is this normal/to be expected? Car is tuned on Ecutek, 98RON fuel. added downpipe, exhaust and intake, everything else is stock.
log can be viewed here...
Which one sounds better? I have a dual exit on catless setup but I've always wondered whether the single would sound better. I've watched some videos online but its hard to really make out the difference. Could someone that has heard both in-person chime in? Worth making the switch?
