2007 V6 Mustang-Loss of bottom-end power

Hi,
When I first got my 2007 v6 mustang, I could just tap the gas pedal and the car would jump. After I installed dual exhaust, the car hesitates when I give it gas. I recently installed a cold air tuner kit which is a cold air return and a modification to the computer. The result was was just a slight increase in bottom end power but nowhere near what I originally had. I was thinking about installing the same rear as the GT to see if it would give me an increase of speed off the line.
I don't know what else to do. I would appreciate it if anyone has any suggestions on what I should do to fix this problem. Thanks for listening.

They have rear gears for the v6, get some 4.10's. that would help your bottom end problems.

You should have actually picked up some bottom end torque with exhaust, CAI and a tune. Check all exhaust connections, and intake connections, you might have an air leak.

i thought going dual exhaust you sacrifice a little low end torque because of less back pressure for a little more hp higher up.

Hesitation 2007 v6 mustang

I just want to say thank you for all of those who replied for my request for help.
I new I was going to lose power at the bottem-end but I didn't think it would be that much. Anyway I can live with it for now but the one thing I can't, is the hesitation that occurs when I stump on the gas. If anyone can help with the hesitation I'd appreciate it. Thanks again

everything is controlled by the computer. to get rid of the hesitation, your gonna need a tuner and tune. i would suggest getting with chris rose at tillman speed, going with a jlt cai,sctx3 tuner/ 3 custom tune package. about 5-525.00. its a very good combo and great price. it will give you choice of octanes, and get the most performance and h.p. out of your car that you can get( outside of a dyno tune)it will make you smile when you hammer it. :shiny: ( the demon coil and livewires made it more responsive too)
