I have a 06 GMC Sierra SLT crew cab Z-71 4x4 with a 5.3 and 127,000 on it, and it needs a cam. I tow a 28 foot trailer occasionally, and would like to put a cam in it that would help this. After the cam swap, and a cold air kit, I will be getting a pc tune to make it all work best it can.

I understand that I need to call a cam company to get the right grind for my needs, but I am looking for information about the swap...do's and don'ts, shortcuts, additional parts that I should replace, how to reset all the internal sensors etc...

I will be doing the work myself, and any information will be appreciated...

Thanks
Dave
