" lol i have used 260gt (100 octane unleaded) from the pump and 260gt plus (104 octane unleaded) from a can before. major difference over pump gas. expensive indeed, but gotta pay to play. "

" In my experience, ams and cp-e have the best flow (cp-e published the white pages and data), while helix and cobb have the best iat suppression. The dinan intercooler has those guides that funnel air to the fins so i'd imagine iat supression with that one would be decent as well. same goes for ER with the cf fins that direct airflow. Really, anything is better than stock. "
