Turbo Tuning Questions

[fleshe]

I have a 2007 Tahoe with a genIV LY5 5.3 and 4l60E trans. It has a E38 PFI ECM running operating system 12614088. I plan on strapping a turbo to it with a BTR cam, 80# injectors, FMIC and a built 4L60E. I will upgrade the 1-bar map to a 3-bar unit even though I wont need it with 15 pounds of boost. I will also setup a AEM Wideband via serial for logging.

Question,
Are the virtual VE tables all I need to tune my Tahoe? I won't need a custom OS will I?

Correct, the 2-bar or 3-bar VVE table (there is no custom OS for boost)... you also need a 2-bar or 3-bar MAP sensor (and you have to edit the MAP scaler).
