Need more power towing

Terry Waldron · 12-22-2012, 01:24 PM

I have a 92 chevy ext. cab pickup 2500 series, has a 454 in it, 373 rearend,automatic. I tow a 22 ft. enclosed car trailer. It is really struggling going up hills anymore, has 57,000 original miles on it. Any ideas to help without going into the motor.

i believe it's Ed Wright you want to talk to. he can upgrade the computer and get some extra ponies and torque for towing, i will be sending him mine out of the motor home soon, (1999 454) from what he told me, it was well worth it

What Keith said-the ecm in that thing is programmed very poorly for power. I had a 90 suburban 454 and a different program made it a new truck! A LOT of lost torque in that factory program.

Terry, our weezed out old 350 would pull what you have easy. Something is amiss. I would suggest starting with a new fuel filter and general tune up. If the fuel filter is getting restricted, it will kill the power.

Yeah,the truck dont miss or cut out just does not have the power for pulling up all those hills going to Earlville,If i see a hill coming up I will get it up to 70 so the time i get to the top of the hill I am doing about 45 or 50.

Does the service eng. light come on?, on my sub. the light would stay on for a couple of min. had no power, scanned it, replaced the o2 sensor, fuel filter, ran like new after that. gsa612
