I have a 2010 Dodge Challenger RT. I recently put long tube headers on and an SRT exhaust. Well of course the car ran crappy. So long story short I think I may have messed with the base tune where someone dead and now I don't know where to start to get it back to normal. I have HP tuners but the learning curve is pretty sharp. Can anyone help me either with the base tune or I could give me a tune for money that isn't crazy expensive?
