TTI headers with Holley Super Sniper? Bung location?

i will eventually go with an EFI system and was leaning towards the bung being at the collector. I'm interested to hear reason to go otherwise....

IF IN THE COLLECTOR , IT CAN GET ITS INFO FROM 1 OR 2 CYLS ., NOT GOOD, PUT IT RIGHT AFTER THE HEADER FLANDE OR CLOSE IS BEST , DO SOME RESEARCH . Also 10-2 oclock position .
