I just did the delete today but my tuner arrives tomorrow, does anybody have any experience as to how long the computer will let me drive until I program it?

 

I wouldn't recommend it

Your ecu should already be recording codes right now since you took your emmisions stuff off. And if you continue to drive it should start giving you a check engine light until you get your programmer.

 

It may go into limp mode. I wouldn't try it.

 

Update: I received my tuner yesterday and had no issues connecting. Playing around with the 120 horse max setting for now, but will set it to economy setting next week. Does anybody know what the HP ends up being with aFe filter + 5" exhaust + EGR delete + 120 setting from tuner?

 

every truck is different. what programmer do you have? and does it have a custom tuning?
