As stated, is there a "best" ECU to run GM TBI with low boost (~8psi)? I have some experience with Microsquirt, and I could use that here. Not expensive, free tuning software, and I can control timing with it too (which is a must). Any better options? Open to feedback/ideas.

Sinister performance.

You can use the stock ecu and get it tuned.  I swapped a TBI from a full size Chevy truck into my 78 Chevy Malibu road race car.  They hooked me up with a tune that was awesome.

 

Edit...  not sure you can use a stock pcm without a distributor.  I'd talk to sinister and see what your options are.  They are fantastic to work with!

A lot of chatter of DIY focused GM stock ECU stuff on http://www.gearhead-efi.com/Fuel-Injection/forum.php and  https://pcmhacking.net/forums/index.php Most of it is LS based  but there is some guys still messing with the TBI computers

gearhead-efi is a great resource for all the GM stuff, TBI and TPI and LT1 are well represented over there
