Guys and Gals I have a question. Im currently buying parts to beef up my engine. Right now I have a TB that I just ordered from TVT and will be purchasing plugs and wires soon. I also have a custom Dual CAI that I have on right now but will be replacing it with a Dual CAI from NW when I return from deployment. How much can I do to the engine before I have to get a tune done. Opened to any information you all can give. As always thanks for your help.
