Ok i have answered my own question. I thought that the caldina were sportier than the RAV4 so i figured why would they make them slower than red-tops? Well i still dont know the answer to that but i do know that they make 190hp or 140KW at 7k instead of the Rav4 which makes 180hp at 6.6K. So i have heard that some greytops have lower compression perhaps its the RAV4 Greytops beacuse of the lower power output? Looks like i might just go back to the greytop! im starting to think that the caldina ecu is the same as a redtop and the power loss is due to the Header only.
