GCP,
No; I have been trouble free since I deleted and I would do it again on my 08. Now if I had a 2013 truck I would not delete the truck. I think with anything new there are teething pains and the 07. 5 and early 08's trucks had them. Since then the programming for the emission system has been change to agree with the majority of the driving style that people are doing.
As far as cost to me the Smarty S67 was $690 and the 5” Turbo back muffler system from MBRP was $637. This is for a 5. 9L Crew Cab Long Bed truck which will fit a 6. 7L Mega Cab perfectly. The EGR block off plates for the EGR was around $50, the EGR cooler is still on the truck. This helps keep the truck warmer in the winter, I know guys who have deleted the cooler and the truck will run cooler then with it on. These are 2008 dollars by the way.
Another point I like to make is the Smarty S67 or JR will work with either being deleted or not being deleted. The only difference is the software that you download to install on the Smarty so you are not out any money on a programmer.

Thanks Jim for the info. I've been very happy with my stock '09, but, like you suggest, most of the issues seem to have been worked out by the time my truck rolled off the line.
