k i have evo 560 injectors in my turbo gsr i had a basemap burned for them, here is what happens, it starts up fine idles for about 10 seconds then rev surges and the idle gets lower and lower then dies, so i tried my old 450 ls turbo basemap and it idles great deosnt surge at all , what could be wrong with the 560 basemap

 

do you have a wideband? I would never run a basemap on a turbo honda without one
