Tunnel ram or no tunnel ram...

The whole size your pv from idle vacuum is false. There’s a lot of times I run a higher PV number than what an engine idles at. You adjust that too where you need the enrichment from a cruise state. You can’t compare the TSR to your dominator. Dominators typically require a smaller TSR due to huge transfer slots.

My order of operation.

Make it idle good, neutral and in gear
Make it cruise and take off like it should.
Then I start worrying about WOT and WOT transition.

Looks like RB and I think and tune very similar.

And for the record as someone always says this. THE PV HAS NO EFFECT ON IDLE A/F RATIO UNLESS ITS LEAKING OR BLOWN.
