Default RC 550 injector tuning

I have a 1.8L with the FlyinMiata turbo setup running ~8psi. Speeduino ecu, Tunerstudio. I had stock injectors running fine but just switched to the RC 550's and now I can't get the maps right. At idle it is at 1 on the VE table and running rich, and at 4000 rpm the autotune jumped it to 250 and still running way to lean. See attached images. Thanks guys, I really don't know much about any of this but had it running pretty good before these injectors.
