I imagine you can use the same methodology with Mikes PI setup that way you don't have to rape the MAF table and throw off the torque model.

But as I mentioned in PM, I don't think you want the fuel transition from DI to PI the same as a PD setup. You likely will need the PI to come in more linear with a Procharger.

I am glad to see Greg was generous enough to share his tune with you and Mike is also helping out.

Mike had recommended using 8000 hz as the start point, and there is some blending in the spreadsheet. Looks like it blends from the start point up to around maybe (start point + 1k to 1.5k hz) greater than the start point. So at 8000 start point, it would gradually blend in the PI from 8000 to around 9400 Hz.
