It's time to change the spark plugs because they are still the stock factory ones in it. My question is even with running a programmer would it improve any performance aspects if I upgraded the plugs to lets say a double platinum or iridium, or hotter plug. Or should I just stick the same ole stock plugs back in it for another 30000 miles. Also, other buddies of mine that have stock 4.7 have been running NGK v-power plugs and they run great, but not sure how they would run since I run performance settings. Thanks for yall input.

Oh yea by the way in case all of yall were wondering my programmer is the DiabloSport Predator U7137, which for all of you that are wondering is awesome and would highly recommend!
Plugs other then OEM won't make any performance difference no matter what the advertisers say. The only difference platnium or iridium would make is you don't need to change them as often as OEM. A spark is a spark lets face it, you would get the same results if you smacked a hammer against the ground. Cause we all know detonation is detonation. What does make a performance difference with spark plugs is the gap. Also timing makes a huge performance difference.
