I am planning on having a 383 stroker built for my 1990 5.7 and plan
on about 300 HP, roller cam, roller rockers,aluminum intake, running
on max 93 oct. The question I have is will a stock TBI system feed
about 300 HP??? Also any suggestions on who is good at burning a new
computer chip, as I am sure with mods that are going to happen, that
the stock chip will not work, even though the truck had a chip change
Hyper tech 8 years ago.
You can find many programmers. You are doing it correctly by starting
with the chip. I'd contact holley and edelbrock and see where they've
gone with these systems, since both do things for TBI's. They may steer
you to a package that's easy to tune. I've had so-so advice from
edelbrock on knowing their own products, but they are good with dealings
on things involving other companies. Seems the help request gets bumped
up the food chain to someone that knows something that way. If you're
really wanting power, it's easier to make it with multiport, btw.
What would be involved in switching a TBI engine to multi port other
than Edelbrock system. Seems to me the factory system MPI after 1995
could more problems, with the stock computer. Edelbrock wants $1000 to
$1300 if I remember. I want to keep this upgrade as simple as
possible, as I live in a area where I can not run down and switch
parts. I do agree about edelbrock, tried for some shocks as the truck
is lowered it was painfull Thanks
