Power difference
I own a 90 Bronco 351 and my son owns a 93 Bronco 351 we both have the same fuel injection system, and both are stock. He has a lot more power for pulling hills while mine is kinda slugish. Does he have that much more HP than I do or are there a few things that I need to replace to regain my power. Both have the same tranny and rear end, and all smog controls. Any ideas?

I know you said same rear end, but same gear ratio? Same tire size? How is the exhaust system on your '90? The cat and/or pre-cat will eventually break down increasing backpressure. Same air filters and both clean? Any codes from either truck?

My bronco has about 110,000 miles on it and his has about 70,000. I was also wondering if an O2 sensor or the TPS could be robbing me of power?
