Removing fuel at wot under boost . I need a basic safe way to to remove some fuel up top on my turbo ls1. I'm running Holley hp efi, at 12 psi I'm fattening up above 5000 rpms to an unsafe rich amount ! I'm taking 7.5-8.5 aft! How much fuel would I want to take away here? Also I have to look at the actual tune but I'm under the assumption that I'm leaving tons of hp on the table , not only with it being insanely rich, but a lack of timing as well. I don't get any Knock at wot . I have the esc set to pull 4* timing if it picks up any, above 148 kPa. My gas mileage is terrible and I'd like to get this thing dialed in tomorrow and doing a hell of a lot better than 12mpg in a m6!!

It has the option to select my exact injector in a drop down menu, which then inputs all the data automatically. It's my boost a pump that's making it fat. You can watch the fuel pressure drop off from 58 psi to 54-55 then spike to 61-62 . I need to pull fuel only when the bap is active

My tune won't do any good without a datalog at the current boost level, which I can't get at the moment , due to a massive winter storm that hit Monday and Tuesday. Last few years we haven't seen snow till the middle of December but this year , it's already here and he car is put up until the roads are clear.
