hi last week i installed my td04l from speedvision and start to run 16psi but have overboost cut.. so we set at 14 psi with internal wastegate, my A/F ratio marks 11.0 at full boost.. the car feels very good but im running stock internals stock injectors just walbro fuel pump of 195lph.. on monday i run 1/4 mile at 13.6s with street tires and overboost cut, i know i can do 13.4 with semislicks and not overboost.. what do you think?? what can i improve?
