No Power Down Low

[Tezstang]

Hello guys I'm new to [=->Stangnet<-=] but not new to stangs.Im on my 7th stang but first 4.6.Its an 07 gt premium.So far it has jlt intake with predator tune . 4.10 gears and long tubes with matching H-pipe.Also has BBK twin plus throttle body.This combo runs great for what it is.Until recently.Ive lost all power leaving from a dead stop.I use to be able to roast the tires just by stomping on it.Now it just rolls off and then suddenly takes off.What happened?Even power braking.same issue.Can some please advise on how to get my low end grunt back.

Any ECU fault codes?

No fault codes.Thinking a 3000-3500 stall will fix this but the car use to leave hard on stock converter just wondering why it started this hesitation all of a sudden

Do you still have stock throttle body? Try swapping that out see what happens.

Have BBK throttle body

 

[SpartaPerformance]

Go find a stock one and swap it out

I still have mine.It use to respond well with the BBK.I could spin into second gear just stomping it from idle.I will try it though and see what happens.
