Will I need an AFC?

[Jason68s]

I have a 67mm turbo on my L36. I've upgraded the UIM to the aluminum intake and will be running the N* throttle body with a LQ4 MAF. Will the upgraded MAF tables for the LQ4 be enough so I don't out flow my MAF or will I need a mini AFC also? I'm going to be running 14psi of boost. My upgrades are 1.9 Rocker arms, HV3 insert and a FMIC. When I had it on the dyno last fall I out flowed the stock MAF at about 4800 rpms. Any help or recommendations would be appreciated. Thanks.

a lot of guys say to use the lt1 maf, its all metal and dont break apart when boosted via turbo.

Yes you probably will.

I'd go with a ls7 maf in a 4" tube instead.

id use a mini afc but still stick with the lq4 maf. my old build I kept my lq4 maf and used the mini-afc. the downside, like others mentioned is the lq4 maf is plastic and I cracked my ONLY cause I overtightened my clamp though lol
