Reflash after adding intake tube w/ OFT tune?
 

Only engine mods so far is a K&N drop in filter and OFT tune (stage 1). If I add a Mishimoto intake tube and increase air flow a bit should I reflash so it can re-learn with the additional airflow or should I use a different tune entirely? Or do I not need to reflash at all with the stage 1? I appreciate any input, thanks.

The ecu may adjust its self enough. But your best solution would be to scale your MAF to suit the new intake.

The stage1 should still be fine with the added intake. But post a few log after a couple days of installing the intake and we'll take a look at it.

Edit: of course you would need to drive during these said days.
