Should I be ok with the current tune or do I need to retune?
It was heads cam tune on it already and only changed to the 90mm setup. Should the MAF make the adjustments for me?

You will have to retune, but I would like one of the more masterful experienced tuners to chime in on HPT side as to how to tune for the new 90mm TB since I will be getting one soon. I know a lot of tweaking will be needed to get idle back into line, surging, etc...
