Hi Paul I know you an expert in scion, i hope u can help...I have 05 scion tc I use to be supercharged, i took off supercharger and put on greddy turbo kit an my ecu still hav trd reflash. I went to tuner an he tune my car with greddy emanage ultimate an it ran fine until for some reason sometime when i drive or boost a little bit an let go the gas the rpm would drop close to zero an car shuts off...it do that sometimes.. the tuner at TE try to set anti stall but it wont let it. Rick at TE say It might be trd reflash but I thought people say u can tune around the reflash. I can still drive an get off on it but the rpm would dropp close to zero an sometime engine would shut off an sometime it doesnt. my setup is 550 injector greddy rs bov greddy turbo greddy emanage ultimate....thanks

Basically you need a new ecu. You pretty much have to get a new after taking the supercharger off. Theres honestly no way around that
