I need to get rid of my ls1 intake, might as well redo my entire induction setup. Current setup is as follows: 78mm lid, stock maf, ported stock tb, ls1 intake. Other mods include: boltons, macs, ory, vig3600, f1 cam, 3.42's

-Gains with 98mm lid, 85mm maf, tb, and ls6 intake?
-Gains with SD tune over using a maf?
-Thoughts on PP 96mm intake over ls6.
-$$ difference from ls6 to fast really worth it?

 

so what is your question?

 

I believe there was 4 questions

 

Correct.
