So its best advised to do this with an aftermarket ecu, after injectors have been replaced\ flow tested
or don't risk it and leave it be and save for a proper one
have a spare plenum in the shed, might have a looksy tomorrow for fins or anything
cos the one thing i always thought was if your gonna move the intake to the front and "lean" out 5&6 then why at the stock position don't say 1&6 "lean" as the air is coming in hitting the far wall and i'm guessing going left and right from there and one would think 1&6 would get more air, oh well as stated will have a look for ribs or fins tomorrow
