I run BR7EF on E85 at 23lbs at .022 gap. Switching to B8EFS to turn it up.

B8EFS on E85 at 1000whp at .022 gap

Also had good results with cheap Autolite 103 on the milder stuff.

Ran TR6s at ~11lbs and had great results. Switched to BR7EFs and upped the boost to 14lbs and it seems to like those as well. pure street car
