I appreciate the response and thank you for the information. I still have a couple more questions:
Could you (for extra $ of course) do two tunes? Ie a 89 oct for normal daily driving and then a 93 oct so when I decide to go the drag strip?
I'm actually planning on just doing shortie headers like flowtech or bbk. LT are nice but I'm not looking to do a whole lot here plus I don't want to hurt the resale too bad.
I can say that once my truck gets around 3x,000 on it, it's going to develop "hemi knock" and the tech (he's a good friend
) is going to find a comp cam 268 in the back seat. I assume that once I do that you can retune then as well correct?
