computer tuning for swap

[quadboy22]

Here is the situation
i have an 87 fiero and put a 3.1 aluminum head v6 in im running the fuel rail and intakes of a 2.8 aluminum head which has been modified to run the disributer. i am using the fiero ecm to run it. i have a kkk turbo which is the same as a garret t3 .48 ar i have 8lbs of boost with a vortech fmu. i am still extreamly lean. i have all the equipment to burn a new chip and wanted to know how much i can increase the pulse width of the stock injectors. or if i should just throw 19 or 24 lb injectors in. also what should i run with the timing i have a msd boost retard system so im not sure how much i need to cut down on spark. any help would be great thanks.

Is your FMU adjustable in any way?

I would imagine the injectors are going static at this point.

If you can turn up the FMU, do that, otherwise, larger injectors.

The fmu is not ajustable it is a 10:1 ratio

What i would do, is get a stock intake, and put the orginal ingition back on(coil packs), use 24lb injectors(for starters) and use a tpg.bin to run it, it will probly be pretty close right out of the box,
