Small gas engine with poor FMIC

[Dust]

Been looking at a Chevy Cruze, as the diesels in the area are higher than I want to go. It's a 1.4L with small turbo, and FMIC behind A/C condenser. The car suffers from timing pull in hot weather due to bad flow through heated FMIC.

I could use the .3mm check valve nozzles i already have. I would like to run at low IDC, but would also like, if possible, to use a larger nozzle for normal operation.

I have a lowest flow FAV, so I think the hardware is there, but wondering if the HFS-3/4/6 can run at low flow, but only failsafe when the big nozzle and 4 DP nozzles are flowing?
