I've read alot of threads, lots of opinions on different mods. Many are multiple mods. My question is straightforward. I've removed carbon filter, changed Air Filter, added RPI scoops. Looking at Dinan stage 1 softward upgrade for the next mod. Those that have done it, do you feel your got out of it what you expected and what did you notice. Lastly, would you recommend doing it? Thanks, your experience in these matters is greatly apprecited!
