    Default Injector swap issues

    I have a 99 LS1, basically stock engine with a turbo, that was tuned by someone else. It had Deka 60s in it and Ran fine with no issues. I swapped in some Deka 80s with no others changes and put in all the injector data and have had nothing but problems. Turns out the Deka 60 data was never really correct as all they did was enter the flow rates and nothing else and it was tuned like that. So now have done nothing but change the flow rates to 80 and at start up it's lean for a bit, then hits 14.7 for a bit, then goes rich. What makes it more confusing is that there is no real change to the injector pulses so I am not sure what the heck is going on. I have attached a log of what it's doing. If anyone has ideas of what to look at it would be appreciated.
