I have a stage 4 port on my eaton with the 2.5 SC pulley and larger pulley off the craink. I have installed the LSP duel flow heat exchanger and still having some serious cooling problems. SCT X-cal. tells me my air intake temp is too high and an over boost condition. I am pushing 18 lbs. of boost. My car will miss once this happens. Any suggestions or advice to help the cooling issue?
