Digital Maf?
The new LS3 Hitachi MAF element is capable of measuring very high flow as it is headed for the blown LS9. As of now only the new 08 PCMs can utilize the 15000hz/1880g/s range. This sits in the LS3/LS7 100mm tube.
I have tried the on my car and the new element logs like it is interchangeable with the LS7 one and generates a nice smooth curve up to the 511g/s table max.
