Honestly, not that much. 10-15hp is the estimated advantage. Not much bang for the buck when you consider I paid $860 for it. But that was 25% off and I had Christmas money to spend, so why not?
From what I've read, this mod should be in conjunction with a set of headers with fewer / smaller cats and a software upgrade. I haven't descended to that part of the slippery slope yet and don't think I will. That would be another $2K for a potential +25hp. I could spend that kind of money at Porsche driving school and make that much improvement in skill.
Not sure what you mean by how will I implement it? I will be doing the change myself and the only dyno I have is a butt dyno. My hope is it doesn't affect daily usage and gives me that little extra push vs other 987.1s. Hope that covers your question.
