Can you find out if the truck has been tuned?

I recently just tuned my truck by ID and now my degas bottle is puking. I'm going to take it in to get arp studs now. If I convert it back to stock tuned will they be able to tell I tuned my truck?

Not if you used the SCT tuner. Your going to need more than head studs by the way.

yes, all they have to do is pull the data logs and see how much boost was being put out. Hopefully they dont

Just because you are tuned doesn't mean that your boost is any higher. I have put out 32psi before I put my programer on while I was towing. Plus high PSI doesnt prove it had a tune it could of had an over boost situation.

and when they see what RPM's it was putting out???
I'm not saying only boost, just trying to give an example of what they look at. They could fix it without giving him problems, or tell him to pound sand

The truck can only put out so many rpms...lol it wont put out any more or less than stock. Thats not what they look for anyways...thats if they even look. I had mine in several times and never took of my programer and they never said anything.

What about when they take off the heads and look at the cylinders? I've heard that when the have the scorched star pattern that means they've been getting more fuel, but I've also heard it doesn't matter if they are tuned they all looked scorched. Which is it?

Do you plan on getting it done under warrenty? I see your truck is an 04, must have an extended warrenty? Otherwise it doesnt matter if you have a tuner or not-i would how ever still put the stock tune back in incase they decide "update" the ecm.

I can not verify that. I think your worrying needlessly though. Put the truck back to stock and drive it in.

This. Don't worry about anything, just take it in. Drive it around stock for a bit and take it thru some wot runs while stock and that should record over the boost and rpm spikes. Not that I believe those are any two things to even worry about. Good luck.
