Im changing nothing initially other than the pump. Wastegates, fuel pressure, everything is staying the same so i can compare loads of past data against the new. I do not know what timing will be set at yet. Was 22* and it was terrible towing. So lower than that. Will still run 5x14 injectors which i can see as being a potential issue up top but idk yet. Im hoping the extra RPM's will allow me to drive the primary much harder. Doesnt matter how i tune about 27psi from the 475 is all i can get. 70psi total. Id really like to get the primary up in the 30's and gate around the secondary a bit more.
