Any help is certainly appreciated. Ive searched all the Googles for several days now. Most of what Ive read involves adjust VE tables, but it doesnt seem like thats right.
My combo is listed in my sig with the only a recent change from Racetronix 160's to Bosch 210's. I have already changed the injector size in Fuel Calculation Parameters. Im also in closed loop and using Flex mode and Fuel Energy Constant at .781 which has worked very well prior to the change. I've also adjusted Injector Opening Offset vs Battery Voltage to the point of it running smoother than ever under idle and normal loads (.60 at 13.6v and .58 at 14.4v) any lower at 14.4v and it starts to stumble.
What I need help with is at high boost at upper rpms. Fuel pressure has not been changed, it now idles at 40psi (was 43) climbs to about 60-70psi under boost (usually up to 80's) but the pressure falls on its nose about 3500-4000 rpm getting near 25psi boost before I have to get out of it (normally 35).
The injectors are obviously going too rich and maxing the pump, the afr's show very rich by 2 points or more. O2 correction is anywhere from +-4 to +-8. I havent logged anything yet, it seems obvious what the problem is. How can I control the injectors back down on the big end?
