[QUOTE="Aaron@JPCRacing, post: 13978025, member: 139397"] Nope you never shut off the 02's in the tune. You just need to be aware of how it effects the car and compensate accordingly. For example, lets say your trying to command .75 lambda @ WOT. But when the front 02 sensors read .75 the car is actually at .78 lambda (just an example) as seen off of your 02 sensor in the down pipe. You'll just need to lower your commanded lambda for it to adjust to the correct A/F. Otherwise tuning will be similar to anything else, its just a matter of dialing in the MAF curve and making sure you've got all the proper data on your injectors (as far as fueling goes). It's not a big deal but its something that you need to be aware of. Again if you'd like to move the 02 sensors post turbine that's always an option as well, you'll just need to modify the 02 delay accordingly. Read through the new 5.0 article if you'd like a 3rd party writeup or PM bench racer or proof101 [/QUOTE]
