When changing from 26 to 28.8 injectors....

[efizjb]

I have a 2000 SS, changed out intake to LS6 and injectors to 28.8, other than changing the injector flow rate chart, is there any other changes that need to be made to the 2000 OS? I have changed the injector flow rate out for one from a stock 2002 file

Car seems a bit lazy and throttle response seems to be poor compared to stock intake and injectors.

Thanks for any help or suggestions, I'm new to this tuning deal. I want to be sure that any fixed parameters are correct before changing any fuel tables based on current fuel trims.

Check out a 2002 tune cause it will more than likely have the IFR and other tables for the 28lb injectors. Compare all the tables in the injector section to see the differences.

yup. copy all the injector related tables from a tune that used those as OEM equipment.

Thanks guys, didn't want to mess with too many tables if it weren't necessary. I knew the IFR table had to be changed because it relates directly to the injectors themselves, but wasn't sure about other tables because I didn't know if the mass air is calibrated different between the different size injectors though the years 98-02.
