I had Hondata running fine and tuned really well but have made a few changes for a few different reasons. I now have a full 3" DP and test pipe(had a 2.5" DP and a 3" cat before), and I'm running .20 overbore 9.2:1 Pistons now(had 9.0:1 stock bore before).
Are there any precautionary steps I can take via Hondata to begin tuning for the new setup? Just add between 5-10% more fuel just to be safe and go from their?
Just looking for some info, a good Hondata tuner wll be doing the tuning but I was curious myself.
Thanks for any info.
