kmr/b2a streetport tuning, fresh rebuild.

I have Mazda edit.
And I have finally got my fresh motor put back in.
Rebuild has
***The built2apex Bridgeport, without the bridge.
So I'd say it's a big streetport. Exhaust is maxed out, literally.
*** Atkins solid corner seals,
**Atkins apex,
**new bearings.
**new eshaft.
*header,catless mid,catback, aem intake
*air pump blocked off.
*corvette coils
Motor ran when pulled out. Before the rebuild

Car cranks an will idle 1500 rpms . But once the car drops to the 800 range it stalls. No vacuum leak, But. I don't have my intake valves hooked up yet. Which these aren't used at idle so that shouldn't be the issue. I'm getting random missfire and idle insufficient codes car runs and revs smooth unless rpms go below 1000

I'm guessing the porting needs a higher idle. Do I just need to start off by raising the idle on my mazdaedit, or should I start with maf scaling,

If anyone has some streetport Maps that I could compare to mine would be perfect.
Is 1200 a good starting point for setting the idle ?


I've also heard of hard starts/ idle problems on fresh rebuilds, taking time to seat the Apex seals to unrefinished housings. Is this true ?
