57trim fuel cut

[stevenr816]

i searched but the search takes out the word "cut" so i got 1000's of threads

all i want to know is fuel cut lower with a 57trim? i would assume so being a bigger wheel but how low? im hitting it at 10psi and the wastegate is shimmed with 2 washers. stock maf/injectors. 3in exhaust

yes since with the 57 trim you are moving more air and the cut is saving you from going to lean on the stock injectors

with 3 letter words use a * at the end and you'll get better results.

I was hitting fuel cut with the stock CT26 and two washer wastegate shims, so yeah it sure seems like you got fuel cut issues. Pull out the shims for now, until you can get the necessary upgrades to support the increased airflow. That's what I had to do. Now my car runs fine, has seven pounds of boost, and no fuel cut. With the 57 trim, you may still get cut, but it will be less severe if you remove the shims.

right under fuel cut with the stock fuel system the a/f ratio at WOT was 10/1 on my car...
