BoostedLS1

Hi everyone. I am after some help with some injector settings. I have used siemens 60's and 80's in the past and they idle ok but I am now using Bosch's new 1700cc indy blue replacements. They are a high impedance injector rated at 1700cc at 43.5psi. I have only tried running these for about 20 minutes as I was pressed for time. They idled half reasonable but as soon as the throttle was applied the car played up and ran rich/lean and stalled. I then put my siemens 80's back in the car which is a stock LS1 on E85 with a s400sx4 and the car made 516rwkw. The injectors are running out in the top end so I want to try and use the big bosch units instead. Has anyone used injectors this big? If so, what needs to be done to get them to behave?
