I am having a few problems with this tune on my car and was wondering if maybe someone could look at my logs/bin file and let me know what they think.
My problem appears to be around 3k rpm when the car seems to shudder like its not getting enough fuel... And sure enough according to the log it appears bank 1 is going lean? Not really sure what to look for here or how to correct it so just looking for some pointers... Sorry logs are with ecux.

So far I have taken the stage 1 m-box tune found on here with no egt's and rear o2's. I altered it for my ev14 injectors and hitachi 94 mm maf. I have gutted pre cats and no main cats.

Thanks for your help.
