Hi guys.... been putting premium gas in my escalade 6.0L since i picked it up last week..... is it alright if i put 87 in the car? Usually by the gas caps in cars it tells you if it needs premium and i checked the manual and didnt see anything.... am i able to use 87?

Regular (87) is all that's required for the 2004 and earlier Escalades.

heck it runs fine in my 07 esv, so yes the 87 will work fine!

The GEN III computers use two timing tables so if it detects knock the PCM will jump to the lower of the two tables. It uses a mathematical calculation to slowly "move" to the higher of the two tables the longer no knock is detected.
Basically performance could be affected but it will not hurt the engine.
