What's going to happen when I start up the new 11.5:1 motor with the 233/239 cam?? I have LS1 edit and I made a few changes in the program when I had the stock LS1. I eliminated the rear O2 sensors because I have headers and no Cats. I eliminated the AIR pump, the 1-4 shift for ther M6, leaned out the PE mode, and have tuned the IFR to try to lean out.
NOW:: I have a new motor ready to crank up for the first time with CNC heads, 11.5 to 1, and TSP 233/239 cam .600 lift. What's going to happen. Is it going to run OK and be lean at WOT, still rich at WOT? Or lean at idle and mid range. Anybody got a good guess???

You'll need to adjust idle, IAC, RAF's, Spark advance (Base, park, and High/Low Octane), VE tuning, MAF Calibration, and the list goes on. It should start up, probably be rich at idle, and then slightly lean out some at PT, WOT sounds like it will be lean since you leaned out PE mode and IFR's.
