Sapper

Sorry for continuing to beat this horse but I gotta ask, Are there any dissatisfied folks out there that have added a Smarty and/or done the deletes? Regrets? I swore I'd wait until the warranty was over on 08' until I did anything aftermarket. Well I'm in the last year of the warranty and planning on starting with a Smarty Jr when that time comes. I may do the deletes as I get braver. I generally believe 'if it ain't broke, don't fix it' and my truck operates great, except for the annoying CEL every so often that disappears on it's own a few days later, but I like the idea of the programmer and it's features. I've followed the testimonials of those that have had great success with the programmers/deletes, are there any nay sayers? Thanks

None. I checked the oil in my truck a few weeks ago with 4400 miles on it since the last change and it still had not turned black. I couldn't believe it.

Huge regrets. Makes you want to do more, and more, and more, and more

See what I mean.

But still so worth it.

Like Blake said, you will hate it. Clean engine oil for 3,000 miles, 5-6 mpg better fuel economy in town and 4 mpg better on the highway. No more "regeneration required NOW" messages and you will miss the leisurely 45 minute drives on the highway while the computer dumps a gallon and a half of diesel into the exhaust and a cooler running motor that will last (although, there are many 6.7's with emissions intact that have 500,000 miles on them still going strong, but all those motors are worked hard)

I would find out what the CEL is for, especially while under warranty, before adding a tuner and deletes.
