Bigger Injectors on a standard map

As per title, what are the general thoughts on this? Not talking a massive increase in cc size, just up to the next level.

what colour have you in now? Do you think you have already reached the duty cycle limit on the current ones? Have you cleaned/ refurbished the current ones?

Why would you want to on a standard car? even on a mapped car standard injectors would run ok

Bigger injectors on standard map will overfuel, I'd have thought.

it may take a while to learn & re-calibrate depending on how much bigger, but the ecu will learn & adjust (within reason) to accomodate for the injectors

Being a 2.5 LPT the standard ones are Red 315cc injectors, the standard map boost tops out at 6psi, so if I were to run up to 14psi (for example) then I'd have thought the injectors would need upgrading. Was thinking of upping to white 350cc injectors.

Would a lpt boost to 14psi?

[quote=leighkaicraigmia;373341]Would a lpt boost to 14psi?[/quote] It would boost to that and more, but it wouldn't be able to maintain the flow at those higher pressures. And I would fit a 16T if I did get bigger injectors.

There is enough room within the trim tolerances for the upgrade to white or blues as they flow the same but only slightly more than the 0280 150 785 browns at around 11% more flow.
