Car stalling in first / Which Scantool to Choose

[VaderDroveGNs]

I have a 1984 GN that was completely stock. I recently did the following upgrades: Walboro340 fuel pump, hotwire kit, billet adjustable fuel pressure regulator, heated O2 sensor kit, 160 thermostat, 42.5lb fuel injectors, and street chip for 91 octane. Since doing the upgrades, the car has really woken up, but i'm having a big problem.

I can have the car at a stop with it idling, but if I don't have the rpms at atleast 1500 when taking off from a full stop, the car will stall out. I don't want to raise the idle, and have already checked for leaks in all the upgrades that were done. So, I think i'm going to need to buy a scantool so i can retune the car and hopefully get this issue sorted out.

What would be the best tool to get this done using the 84-85 ECM. Most of the scantools I looked at online were only for 86-87. If anyone knows which ones would work with my ECM/where I could get one, it would be greatly appreciated. Also, does anyone have suggestions on other reasons the car may be stalling in first?

Thanks a lot for taking the time to read a newbie's post.

what chip do you have ? was it for the size injectors? If your looking for a scan tool your gonna need a 86 ECM from junkyard donor. I don't have any scan tool as of yet but I would get the Scanmaster street level, powerlogger for bit more (IMO) TurboTweak - Turbo Buick Custom Chips and Parts
When you get the 86 ECM your gonna have to get 86/87 MAF also, or upgrade to LT1/LS1 MAF with translator.
As for stalling, What's your fuel pressure at idle, is your IAC/TPS set or working ok?
