ECU/ECM Fuel Injector Help

Okay so I took my 2000 Jeep Cherokee Sport 4.0l to a concert on the way the thermostat loced up causing the motor to over heat but i didn't wanna stop right away cuz i was on the thruway and had alittle way to go to get it off...I replaced the thermostat, water pump, and radiator, then i had some work done to have 3 piston rods replaced a head gasket and the number one fuel injector. the guy who did the work said that my injector computer was messed up heres what happens when i drive it.

from a dead stop i shakes alittle bit when i begin to accel, then it rides smooth till about 40 or 50 when it it loses power and acts like it can't shift gear or begins to accel and decel like the injectors and over firing and under firing

he told me he hooked it up to a test computer and it was running fine but i dun trust that cuz he didn't really tell me what was fine about it.
