TBI Injector DC%

[Fast355]

There is an injector constant which represents injector flow and engine displacement. Typically changing this constant alone is not enough to address all performance changes that occur because of pressure changes.

TBI PCMs like the 7427 have an actual injector flow value in the constants. Like you said he will have to make some changes to straight pulsewidth tables like cranking fuel and AE to name a few. Might also have to adjust the injector compensation table to keep the VE table from belling and proportional gains to keep the engine from surging.
