tom i have 42lb inj now and i want to go to 50 or 60 after i have the tune running well on the 42's


i know i have to change a few things

fuel inj breakpoint for the 42's is 0.0000166
so this would need to be changed to 0.0000198 for the 50's


do i have to change the low and high slope
aswell as inj comp batt volt


so i would take the current maf cailb of 42lb inj and diviide it by the inj size that came in the car (19) so........42/19=2.21 and this should be my ratio and multiply that in the right hand column of the maf tranfer function for the entire column this should get the maf counts close

thanks for your help tom
