Just installed an FP Black and got a tune. We're running a conservative 23lbs of boost because we're having problems with my DW 1000's on AZ 91 OCT. No matter what my tuner changes, the injectors pulse width keeps jumping to 12 ms at WOT. In turn this riches my AFRs out to less than 10:1 (as i have the AEM Digital Wideband) and is so bad that my car cuts out in the high end. He has no explanation of this and we're waiting for a response from Cobb to see what the issue might be. Anyone have an ideas?
