Posted over on tech but no feedback, so thought I'd try here.
To bring everyone up to speed here's what I need help on. The car is a stock 6.0 LQ9, stock injectors, stock 4l60E/no stall, SLP Lid, Pacesetter LT/ORY no Cats, 3in all the way back to a muffler, 3:42 gears, 17x11 with 315s in the rear.
The ECM I picked up a few years back was believed to be stock but isn't, seems it was tuned previously and I have no idea for what combo. My question is will the current tune be too much for my stock set up and possibly hurt the motor? Below is First Scan of the ECM, Base tune from the shop, and a limited drive scan (car is waiting to be inspected so it limited my driving abilities). Thanks in advance!
If there is any information I've left out or that is needed please feel free to ask, as I am just beginning to learn to tune.
