Anybody have MAF scaling values for HKS intake tube??

[GeneralTJI]

The HKS short Ram intake, using it to build a custom cold air intake into the fender.... Most of the aftermarket tubes I've seen need some tweaking, just wondering if anyone has some ballpark scaling values I could run??

...and thank you very much!!

EDIT: my signature didn't show up?
