Tuning for FI with DI or PI - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

So of the various tuners that we have providing ECU tuning for Forced Induction setups, which ones are relying on tuning Port Injectors versus Direct Injectors for fuelling?

I know FullBlown uses both port and direct injectors with their kit.

I see no reason to not use both. DI has great benefits. As well port injection enables us to run much larger then factory injectors for the higher fuel needs. I prefer and use both.

you end up using both in the end. but some choose to use a higher % of either system. swing towards one side more than the other also has slight issues its all about a happy median

Di is always better for making power but the di injectors are not big enough to run di only i think
