After having this upgrade for a year it was working great, it has saved me alot. 1. boost controller went bad and she boosted up to boost cut and it stopped me. 2. i was on a dyno where they tried over loading my car and the boost cut saved me again(they did the same thing to a rx7 and blew up he motor).. but recently when i shift very fast into 2or3 gear it hits boost cut sometimes. I am only running 12 pounds of boost so it shouldn't be a problem. i moved the screw out farther than i have wanted to and i am still hitting boost cut. i am just looking for some answers. Do you think there could be dirt or oil on the mafs?
thanks for all the help

sorry i should have checked codes first but any way. i am throwing codes 51/34.. i also found out that my tps might be bad.. so i am going to check that out and see whats going on.. could it be that the comp is not reading the tps and thats why i am hitting boost cut/fuel cut?

Do not take your car to that person again. Any tuner who pushes your engine beyond what it is capable of, is retarded. I know a guy who will ask you for every single modification you have done to the car before he touches it.
