It's a choice of low cost OBD1 vs. high cost OBD2. The original 7.4L Vortec was OBD2, and the '02 Escalade is also OBD2. In my humble opinion, the performance difference between OBD1 vs. OBD2 is OBD2 worth the added $$$. The downside to OBD1 is the steep learning curve to achieve near OBD2 performance. OBD2 tuning software is more user friendly with a less steep learning curve compared to OBD1 tuning software. Learn a lot, save a lot of $$$!

At this point it's mostly just weighing my options and seeing what route will give me the best expandabity. I want to go efi to have the ability to tweak it without having to rejet a carb or swap out a cam just to change a variable. Not horribly worried about learning tho, always up for a challenge!
