If you run larger injectors and the ECM doesn't recognize, isn't that problem enough? I never had any problem breaking the tires loose in 2nd gear, sometimes in 3rd gear if I had the right combination of RPMS and actual speed as I shifted into gear. I would recommend removing the spark plugs and inspecting them, maybe cleaning them a little, they may be a little fouled with the extra fuel running through them. Let us know how things go.
