chevy t.b.i question

[bowtiy]

i'm gonna install a 1991 tbi 454 in my 1995 tbi 350 truck, will i have to switch to a computer for a truck with a 454? i know that it will run ok with the computer i have, but will it starve it for fuel with the 454?? just wondering if anyone has had experiance with this..

if learnd alot lately about the tbi systems by swaping a 89 350tbi motor into a 69 chevy p/u, and they are not like the newer fuel injection where you can program the computer to have a longer duration pulse to the injector like in the 95's, the 91 models actualy were different size LBS for the different motor sizes , you may have to do someting like repogram you ecm for a longer pulse to give the older injector time to open completely.
