So I tried to use blm locker on my tune in my 94Z. For some reason it doesn't work. The car still won't default to 128 at WOT on the left side. Any ideas why that is?

 

anybody have any thoughts on this one?

 

Low fuel rail pressure. The LT1 fuel return regulator that is located @ the end of the rail can cause a low pressure zone. I still run an in line system, but, moved the regulator down stream with -an fittings and flex hose. In my opinion, this really helped equalize pressure distribution in both rails. I'm running 72# Siemens peak-hold injectors on a LT1 383-FI app. B.
