Still have the dual kit..I have one of the first ones offered on the C5! Would like to make it run more efficient if possible. :coo:ZO6 AL-X said:Single intercooler is a lot better. That's what Andy did with the ATI kit. I heard he gained 60 rwhp with that swap alone. He first did that a few years ago, I think.
I know that he sells upgrade kits for his setup. Is that the same as you have?
