I was very clear. Is it based on the gt28r or the gt28rs? The response was at first, "They are GT28's." I said, no r or rs. He said, R and I told him I was looking for the RS because I like the newer design. He said you guys had lag issues with the gt28rs. And now your stage 3 turbo is based on the gt28r. Now you say otherwise.
If this is true, fine.
But you can see how I would be confused as to what the 10 stage 3 turbo kits on your shelf really are when I get conflicting information from your shop.
