I have been using Waynos 3" Perrin MAF scale for a week now and my numbers aren't looking that much better for LTFT
I want to start scaling the MAF myself but it's like -18°C outside right now and I have seen multiple recommendations of doing scaling when its 20-25°C..
What I'm thinking is if I flatten the IAT Compensation tables can I effectively do the scaling now? Or am I wasting my efforts considering how cold it is. I would rather not reinstall the OEM intake. And really hope I don't have to wait till it warms up to do this as I am still seeing up to -20% at times and it bothers me a lot.
Thanks in advance,
