I have a 1994 7.3 with factory turbo. Added a hypermax intercooler. I feel like I have a huge loss of power (not because of the hypermax). I am basically flooring it and my truck maintains a speed of 65mph with rpms of about 3k when towing my 18ft boat. Is this normal? Do these things really not have much power? I just had the transmission and engine rebuilt and its the same result. I won't even think about pulling a travel trailer with it.
