Hey everyone im waiting patiently for my 3.4 mps to come in tommorow along with a tuned pcm from Reptile wednesday which im sure will be nice. Right now im just running my headers and cai. I got the plugs and stat all ready to go. Along with a new coupler and oil. I'm just getting pretty anxious to get these all on my baby. For people with a 3.4" or for whoever had a 3.4 and went lower, how noticable will the pcm and drop from 3.8" to 3.4" be ? Will i get sucked in my seat a lot more? lol. Just anxious to see![]()
