Have a 94 t800 with a n14 rated at 330 hp and 1350 tq with a 9spd eaton. Whats the most that it can be turned up too by a ecm flash? Truck is used to pull double bottom dumps so its always hauling heavy loads.
That depends on engine hardware, you may have to change injectors and turbo to get more power. Best to have someone run the engine serial no. to see what needs to be done.
