4 X 1680's set up?
 

I thought I posted this earlier so I will try again.

My last motor I was seeing mid-high 80's duty so I upgraded 1000 primaries to 1680's as i need more room. I know a few drag racer use this combo hince why I posted here. I need some advice on getting this to idle decent and be some what drivable before the tune to make sure all is well. Running a PFC now but may swap to AEM for the tune. I have tried a few recommended settings but was no better.


Any help would be great.
