I'd get in touch with XPT folks and ask them. By default most people on here would say you would need to tune for it, some intake manufacturers used to claim for some model years (like yours) that their intakes measured identical to stock but it's not something I'd trust my motor to. My guess is they will tell you EXACTLY what the map notes say.....prolly gonna have to rescale the maf in a tune. Since you already have a tactrix you are situated to get a etune scaled specific for your car so you can save some dough if you really want to use the AEM intake. my 2cents
