To me adding a JB or PROCede ontop of a Dinan stage II or III makes no sense at all. And I am talking technical. Choose one or the other even if you want to dump one you already paid for. Two half tunes does not make a whole tune. For starters, Dinan is not cheap, especia$$y stage $$$. You get a better tune if you go all Dinan, all JB or all PROCede, than you are getting stacking stuff up. Just don't do it. You guys did not see that hirallious thread where a guy on here had problems stacking JB on Dinan and then tried to blame Dinan..?
