If a car came stock with 270cc injectors then you upgraded to 370cc injectors (10% bigger) would one set the SAFC -10% (tricking the computer to thinking there is 10% less air coming in causing a 10% decrease in fuel flow) across the whole rpm range for a rough/base tune or am I not seeing the mathmatical complexity in setting the SAFC?
I ask this because that's what I did and my car falls flat on its face at around 2500rpm and it doesn't pull on the top end.
