How would a TBI setup react to boost?
Well there would be a couple of considerations:
1) you would need to boost reference the pressure regulator which is typically built into the TBI unit.
2) TBI injectors typically run at 15 psi, depending on which pump you used it may need to be swapped for a port injecton type, as it may not have enough pressure capacity to keep up with the boost referenced regulator.
3) For mild boost applications it would most likely be fine, you would want to ensure the injectors are big enough to feed the motor.
The '84/85 Ford 302 used a CFI (ford's TBI) that actually used regular port type injectors so for a boost application this may be a better choice as there is a much wider injector selection out there. Also this unit will bolt on where a motorcraft 2bbl carb will fit.
