Not really, the TBI delivers fuel the same way as your carb, it's a wet manifold system. I'm running TBI on a 377 cu in (383 without being bored to 4.030") stroked Blue Print short block with aluminum "fast burn" style heads that flow better than Vortec. Running at 10.3:1 compression. I have it rev limited to 5700 rpm (until I get it broke in) and no "backfire" with ~12.5 AFR on my WBO2. I'm thinking your "backfire" was really lean pops. What AFR are you running at?
I can "tune" my TBI with a laptop, not with a screwdriver and wrenches. Everything in the TBI is replaceable or serviceable. I have an AFPR so, if I want more fuel, I simply raise the pressure or adjust my VE fueling tables.
I don't wanna get into a pissing match but, carburetor technology is older than TBI and way harder to "tune". Why would I want to revert back to the 70s when I was first tuning carbs?
Enjoy running your toilet bowl system, I'd rather be running a computer controlled toilet bowl
I believe metered air leak is the term you're looking for.
