sct x4 tuning vortech v3 si supercharged 05 gt
Hi I have a 05, how do I tune it. I was tuning around with my new tuner, under the fuel injectors there are ,stock ,30,42, but I have 39lbs that came with the SC, should I just use 42? And when I tried 4%,8%,14% more air/fuel ratio the car vibrant at idle , what's wrong? Like someone play bass drummer at engine idle speed. Under air filter , the SC also has its own version of pod filter, cant identify and adjuest on my tuner, it has many options like BBK, K&n, car only has whatever the SC same with, and outlaw exhaust ,no other mods. So if you have the same set up, can you show me how you using sct x4 tune your 05 gt?
