PGsigns yes lots of guys are finding carb replacment style efi bolt on stuff is liking single plane intake's over dual plane . one guy over on my other site i hang out at has done a dyno test in the vehicle to prove it . also he did a plug read with old dual plane and then with single plane and found better more even results on the plugs . i guess this is 1 reason why edelbrock has done the single plane from the start on there pro-flo systems , and they just move air when the fuel is port injected .
few guys on my other site are removing or have removed sniper / fitech and gone edelbrock pro-flo 4 system and say its much better from the start . 1 guy on edelbrocks forum said he had to do way less work to drive it tuning wise than the sniper he had and its running better 2-3x faster than the same amount of timefor the sniper .
i think we all need to join together and create a web site ihateboltoneficonversions.bullsh!t
