From what I hear, you can feel the sprint booster in real life driving. You will not feel any gain from the AFE unless you have an extremely sensitive butt. I am still a non-believer of the AFE system tho I may be flamed heartily for this comment. Until someone can show me how the open air element with a skull cap is shielded from engine bay heat soak, I will continue to refer to the V8 design as a HAI.

Both!

IMO...Sporint Booster first, intake second.

I would go wit the sprint booster first.

so you would know how to control the gas pedal.

when you save up enough $$$ go for the rest

Afe intake & remap ......pretty sure you can get a deal on those two.
