With stock injectors you are on the right track for the tunes. not sure how heavy you will tow but you may want to get something in the 40HP range for towing heavy. I really like the High Idle if you have an extra slot on the chip. you can choose the RPM for it too. I have not tried yet but was thinking of setting the max vehicle speed at like 1 or 2mph so its good for warming up the truck and if someone decides to try and steal it, they will max out at 2mph and hopefully abandon their theft attempt in short order... no start is another option but Murphys law says you are going to have the truck stolen the one time you don't switch it over to no start.. If you go with the FU package you can change these at your whim and it really is a great deal....
One reason for the no start is if you go with a different PCM code than stock you cannot use the PATS system, then again your model didn't have it in the first place
