Hello everyone. I recently got my car tuned by a very reputable tuner, and the car was running great, except that my 30lb injectors were maxing out. I went ahead and swapped out the 30's for 42's, and now have to retune the car. I already changed the injector constant, and was told that this would get the car driveable, but not fully tuned. I can tell the car is running rich, because the throttle is not crisp anymore. The car is tuned, to run in open loop the whole time. My problem is this, the tuner that I use is 110miles away from my home, and there is local dyno facilities to me. I also have lt1 edit. Is it that complicated to retune, or "clean up" this tune, if I were to do it myself, being that it runs in open loop the whole time? There is only one table correct? Any advice would be greatly appreciated, as I am trying to make it to the track this weekend for a GM vs. Ford Event!!

 

If I remember correctly the voltage adjustment for the injectors (don't know the name in LT1 edit) will need to be fine tuned. Please correct me if I am wrong, or add what needs to be added please.
