You can google copy and paste all you want, that hardly makes you a "educated smartass". Do you have any real world experence? I do. I have a fastman tb with a bored tb spacer that was tuned on a dyno. (Heavily modded Golen 4.7)I put on a 99+ intake, tb, spacer and headers and I gained 15hp. I can guarantee you none of that came from a spacer. I wanna see your real world results on jeep.
Way to bring the thread back off topic we all know... Jeep 4 powaaa is 2lgt 2qt!!! Lets see some of your dyno spreads or are they in your build thread?
