Luckily so far the engine has actually ran pretty smooth. No surging, it starts on the first turn every time and today after welding up my full exhaust system, I ran it again. This time I ran it long enough to get it to operating temp and it went into closed loop a few times. It appeared to be running pretty rich, I logged some data and will post it tomorrow. I'm hoping I can get it out of the shop and put a load on the motor this weekend. I would like to get a WBO2 but I've run my truck fund completely dry. Any nickel and dime parts have to go on the credit card for awhile. Every evening I've made progress. And seeing it go into closed loop and be rich made me happy tonight.

Set your injector flow rate, add the vortec timing table I posted from the Suburban I tuned last summer, and then start working on you VE tables. You can put my timing map in both the off-idle and idle timing tables and take the value from 1.15 or 1.20 of the Equivalance ratio vs spark table (they are the same) and put in your PE spark advance table.
