I have an '03 300A, I want an SCT-2 with your tunes in it. I am stock now, but plan on a 92mm MAF sensor, a dual 65mm throttle body, and my own cold air intake. Later I may go to 4.10's, larger injectors, and nitros. Can you give me a good street tune for this combination? Also I have 285/50/18's, and want the speedo recalibrated.
