Personally I would change the Target A/F map for WOT operations only (start from 4psi or higher). When you let off of your throttle, there will always be an intermittent rich spike which will throw off the Target A/F map. If you choose 95% TPS setting must be true for the Target A/F map then you won't have to worry about this intermittent rich spike. Besides closed loop operation is already taken care of by the stock ECU, so no need to do this twice.

Yes you were definitely right about being rich in the upper end of that. I finally understand how to use the datalogging feature and actually read it when Im done. Here's a modification of that tune and some logs to accompany. Should I be aiming for a specific A/F ratio throughout the entire powerband?
