Ir would depend upon whether you want to go with a MAF or with speed density (SD). Maf, use a '165 and $6E code ('89 MAF code). SD, use a '730 and $8D ('90-'92 code).
Can't or shouldn't use the current ECM. It isn't setup to correctly run a port system.

what are the differences in the setups? which do u think would be a better choice? or does it depend on the year of the TPI system i put on?

SD doesn't care which intake is used.
Early MAF needs matching intake or code mods.
Late MAF doesn't care either.
Provided you do what is needed for the 9th injector if applicable.
