93 Octane

Had FLKC of 0.91

first pull after 1k miles with 1/2 tank of good premium gas.. car felt fine but after checking logs I see FLKC values being almost +1. Im using the stock tune with catless headers so im thinking thats causing an issue however the stage 2+ tune ive been using has caused fuel trim issues. Now I just downloaded the new 4.03 files from OFT for stage 2+ and I will be flashing that now and getting more logs. The car im running has CP Carillo 10:5:1 pistons, skunk 2 rods, all rbuild but the tunes def gotta get done soon. hoping to have the money for it all this week hopefully.
