Re: Need more power towing
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

Re: Need more power towing
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.

Re: Need more power towing
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.
