Last time I sent them both PM's about something else, I didn't even get the courtesy of a reply...

Thanks guys, this puts my mind at ease somewhat...if the ECU is going to relearn stuff anyway, then that's great.....I may well end up getting a J3 down the track anyway, for $200 a customised tune sent to me, and this can be further refined on a dyno...

'Power' mode does hold revs longing before changing....designed for towing or when 'economy' mode is just too slow I usually drive in power mode as I find a minimal difference with regards to fuel economy when not being crazy. I also find the transmission also kicks down more readily and this helps with things like overtaking etc.
