Hey all.. so long story short my car was just finished and when I went to street tune it with the builder the car would randomly have the injectors go to 100% duty and the a/f pegged at 10 on the afr.once this happens if you reflash it it would be fine for 10 mins or an hour no telling when it would do here's a guick build sheet of the motor... Please any help would be great. And we did try another ECU no difference
