no, when you get a bunch of bolt ons under your belt a good tune would benefit you then, but not just yet

If you have a 99-00 with 26lb. injectors, your long term fuel trims will go way up and your injector duty duty cycles will get pretty strained at WOT. I just swapped to 28lb. injectors and flow rate, and it brought the LTFT's and INJDC's back into line. I'd recommend going to bigger injectors and changing the IFR table when you swap the manifold.
