2000 Chevrolet Cheyenne 5.7 vortec power loss
So I have a 2000 Cheyenne with the 5.7. Just like a Silverado but it’s the Mexican version and it has a 5.7 instead of the 5.3. Today I got stuck on the side of the road because the ignition module decided to go out on me. So I’m around checking some fuses and realize that the injectors fuse was also blown. I didn’t have a 15a fuse so I temporarily put a 25 one in there. I towed the truck over to a friends shop and he let me get a used module and I turned the truck on, let it run for a couple seconds. We tightened the sensor on and then I changed the fuse to a 15a again. So I go to test drive the truck, and for some reason it felt as I was driving a v6 with bad spark plugs and -25° on the timing. I floored the pedal to make sure it was running fine and the truck doesn’t go past 4K rpms and doesn’t shift up either. The truck used to perfectly also. Whenever I floor it, wether I’m at a complete stop or going 30mph, the truck goes into overdrive but the rpms will go up far too slow. The fuel pump did give me some problems a while back, but I just smacked under the gas tank and it hasn’t given me problems since. Whenever I’m parked the truck will get the Rpms up fairly quick but I just see it stalling in a way once I romp on the pedal. Any ideas as to what it may be? The truck idles perfectly also.

Cheyanne was not always a border jumper either. Used to be a downgraded basic Silverado. Cruze is garbage as it's made in Mejico too.
