Hello.Items installed on car,BBK cold air intake.shorty headers.BBK high flow x-pipe with high flow cats,Flowmaster exhaust,off the shelf computer chip.Smog pump eliminator.Items to be added later.Intake manifold,larger injectors.larger MAF sensor,cam,and aluminum heads.I would love to add a supercharger,but not in the budget.I liked the Hyfire because it stopped the car from stalling when i stepped off the throttle.Disliked it because it is very sensitive to outside electrical interference which would trip the box out causing the car to stall.Turning the key to off would reset the box.
