Just a few questions before I sink $'s in performance items. Is there any hard data showing the increase in HP/torque by having dyno sheets before and after mods, this is on a 4.0 V6. Also how do the changes effect MPG. Also I have a 2005 ST Premium.
1. SCT tune or tune otherwise.
2. Same question with headers.
3 Same question with cat back systems or duals.
4. Same question with CAI
I have done some checking on this site, other sites, and vendors and am not coming up with any info. I am new here so if these questions seem ignorant, they are.
Oh yeah forgot, is there a how to make your own CAI on here with parts lists and such?
Thanks up front for your help.
