big port head

[goble]

then yes it will need mapping. you got bigger maf on?

 

[goble]

also change your dv to the cold side

 

[h17och]

ive been meaning to do cold side DV

how cum you siad i need it with big port?

currently have 3" maf

 

[goble]

its better with both small port and large port as it doesnt disturb maf to run weak causing it to burn out

 

[h17och]

currently getting hunting idle. been told its due to not having cold side.

that sound right?
