tuning injectors myself


Getting 30lb injectors and a 255lph fuel pump installed and on my sct xcal-2 there's an option to change your computer to accept any injector from 19lbs to 60lbs. So if I plug it up and adjust the tune to 30lb instead of 24 that its on now, and adjust the a/f ratio some, shouldn't that make it safe to drive UNTIL I can get it dyno tuned next week or so, ill only put maybe 60-100 miles on it, big maybe, might only put about 30, depends on the weather.

you should be fine, although i dont recommend doing it. If you have a A/F ratio gauge, switch to 30lb and keep an eye on the gauge and take it for a test run, regular and then a smash run. If it goes too high or too low, ride a bike.

Heres the deal

I rode around in my car with 30lbs, calibrated mass air and boost with no tune for 3 months.

Dont get on it past half throttle.
Take your time
Think about what your doing with the throttle at all times
dont spin it over 3k
listen for detonation
