    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?

    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.

    it might throw a fault light if it has to adjust the ecu parameter's too much to get it running right, but you soon get used to ignoring it lol

    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.
