I don't profess to be an expert on EFI but I'll answer your question with a little history. My 54 Studebaker has an 89 TPI 350 vette setup which I installed by modifying a couple of OEM wiring harnesses and having the Chip re-burnt to eliminate EGR and VAT. I also had the vette ARAP code burnt in also. It runs and starts fine but I don't have enough miles on it to really access it. My attention the last two years is my 355 SBC Avanti which I built to rekindle my muscle car Jones. It has all the speed goodies and my original plan was to use an Edlebrock Thunder Carb which I installed. Could never get everything just right although it would run like a scalded ape.

Decided to convert to a Holley EFI Commander 950 TBI setup to allow more flexibility with it's programmability. Got a great price from a friend and installed it. The standard programs ran about like the carb, well but not perfect. The programming was just more than I found I could deal with.

Decided to make life easy and sold the Commander setup and switched to the Holley HP EFI setup. Put it in and it started and ran better than all above out of the box. It continued to learn and when I downloaded the results of the computer programming itself, I was surprised how far the timing and advance were from what I thought would work.

As far as the system you asked about, it looks like an less expensive Commander 950 setup from a GM box.

My opinion, You are probably just as far ahead to have a chip burnt with a decent GM code to fit your motor.

But for my money from my experience, I'll take the self learning Holley/FAST setup with the wide band O2 setup. This is the technology all of the newer cars use to control engine parameters and represents state-of-the-art and the safeist technology.

Sorry to run on but I hope this helps to explain why I continue to support the newest technology to minimize the issues you are worried about.
