165 ECM and 80# injectors lean issue
I'm currently running OSE 12P in my turbo sunbird with a gt2871R turbo, 80# Siemens deka injectors.
Previous combo was the same except with Ford 42# injectors. At 22 psi those were static hence the change to the deka 80#.
Having an issue now starting at 180kpa the engine starts to lean out bad. I've added alot of PW to the point where these are static and they flood the engine. Fuel pressure rises with boost and doesn't fall off at all. Now I'm wondering if the injector driver is not up to the task considering the Ford blue Bosch 3 injector ohms were 14.5 and the dekas are 12.
Help?
