I have found Dinan is a very honest company. If they don't think it's worth it they don't sell it. Even if they could.

Are you running more boost than factory? Are you tuned with cat less down pipes? If so what were your before intercooler and after intercooler temps on your runs? What were your temps at the start of your runs and at the end?

The tune is going to be your best bet. Which one are you considering?

I doubt the canned off the shelf tunes would maximize these but I am getting a custom tune on a dyno so the ability to maximize the cooler intake charge is there.
