what year is your car? I have an 00' which had the 26# injectors and I'm pushing 90% duty cycle with not even full bolt ons on the stock rev limiter. general rule of thumb is to not exceed 80% cycle so I would plan on upgrading them to be safe even if they're the 28# just because the last thing you'd want is to not have enough fuel on a dry kit
