    Ive seen that getting the 2.75 upper pulley is pushing the stock fuel injectors

    This would be a good question for top cat.. I'm sure he knows what the injectors are capped at..

    I've done both and had to step up to ID1300 , getting tuned next week and should have some more info then . Duty cycle was to close to leave the 1000cc in there so we will adjust the 1300cc accordingly

    For now yes , we are running a BAP but may switch over to a dual pump setup if needed . A few cars I know are running more boost than I am on stock pump alone " Texas cars " from what I learned . Should be in your neck of the woods ...
