Ok long story short we took my wife's 13 Gt auto and added a vortech, JLT intake, ID1000's, BAP, O/R X pipe and outlaw axle back kit. On the dyno the car made 8psi...598hp/489tq which is respectable.
The issue is I'm new to these cars and still learning, I'm old 5.0 and lightning guy but love these new mustangs. So the car has some hesitation and jerking motion at part/mid throttle, almost like its loading up and in between making boost and shifting (hard to explain but breaking up some). When you give it a little gas its lines out and is fine and WOT is fine. Looking at the dyno graph I was surprised how the graph looked, its jagged as hell all the way up like a jig saw blade, as to where I am use to a very smooth graph. I was told all these cars have similar graphs with the variable timing but I am skeptical this is correct. Anyone else have these issues with drive ability in an auto or jagged dyno graphs??? Tuner is willing to fix but I would like to know for myself what's possibly going on here. I am assuming the TB and MAF need some additional tuning but not sure.
I have ordered a torque booster kit that should go on this weekend since I wanted more low end torque and a little more hp and was hoping it my help with tuning this issue out as well. Any advice or comments are welcome...
