I used your MAF scaling with my Typhoon and the LV was a mess. I ended up reinstalling the factory air box and scaling, set my scalar and latency for my DW's then used RR to rescale the MAF again. Rinse'd and repeated the MAF one more time and got it right.

 

I think with stock injectors your K&N scale is a great place to start, but in my recent experience lately the MAF always needs tweaking, even the stock MAF scale is iffy on some cars.

 

I guess you could say it is a result of "every car is different" theory? Your thoughts Mike?

Remember, you gave it to me when I was playing with the romraider maf scaling tool. Probably almost 2 years ago now. If the data is no good, I will delete it and ditch the file. You know far better than I.

 

But those are the values I started with and had it dialed in after a nice drive to Irvine using the tool.
