When upgrading your plenum and TB is it necessary to change the MAF or the intake piping to get the maximum gains from this mod? I have installed the Accufab plenum and 70mm TB with the stock MAF, MAF/TB tubing, and stock airbox w/ silencer trimmed and drop in K&N. I was just wondering if getting a MAF or changing the MAF/TB pipe would be better??? How can I enhance this mod?
