I have a simple question. Will it be worth it to have my car dyno-tuned? I know trifecta is the only tuning option when it comes to custom tunes so.... Has anyone with trifecta gone from the simple plug in tune to a dyno tune and noticed a difference? I just want to know if it would be worth it. I'm planning on getting headers soon and wanted to know if I could stick with the plug in tune or if I should splurge and do it on a dyno to get the most out of my mods. Thanx!
