Re: New 2010..
You will be much happier with a custom tune from blackbear or nelson or wheatley than a programmer. The cost is somewhat comparable, the results are night and day difference. I have a bro-in-law who insists on the programmers because he trades trucks like changing clothes and they do nothing for performance compared to the tunes I've had.
