What would be the best prom image to start with for this configuration? It's going into my 85 tbi converted Chevy swb truck running a 1227747 ecm. It's a built up 91 tbi 350 truck enigne. With a set of fully ported and flowed 601's (similar to the 416's), ported Edelbrock Performer RPM 4 barrel intake, 1 5/8" full length headers, 2.5" true dual exhausts with x pipe, Comp 268h camshaft, split ration 1.5/1.6:1 aluminum roller rockers, 350 tbi unit with all tbi mods (not yet flowed but will be before installation), running a tpi fuel pump set @ 19psi on stock 350 truck injectors, backed by a 91 truck 5 speed with short throw shifter with 3.42:1 limited slip rearend. I know this setup is pretty similar to what alot of people are running in their Camaros so I figured this would be a good place to ask. I already have all the tuning programs and equipment needed just don't know what prom id I need to start with. If any one has any ideas on how to make tuning this a little easier I'd really really appreciate it.

Thanks,

ASDU is a 5.7 L auto trans 1991....
ACSW is 1987

ARHT is a 5.7 manual
ASDW is manual

I would think manual is the one as less changes need to be made but auto will work too.
Not sure of differences betwenn ARHT and ASDW. search....
