vortec head fuel map
 

Hi all, Ive completed a marine head and intake conversion to a 4.3 w motor (in my astro)and have struggled to find the relevant info for spark table and fuel map along with injector offsets. Ive searched the forums and found spark table info posted by tunertech for the 350 and put those values in tunerpro but to dial it in further I could ideally use a fuel map too if anyone can help? also injectors are bosch ev6 (885176 0280156081) and I have found flow rate with stock 4bar fpr but unable to find any offset info so if anyone knows this too that would be awesome !

Thanks for taking the time to read this
