Custom Tune for 05 Mustang GT Stock w/ Ford Racing Stingers?

[CJs197]

I was wondering if there was anything that could be done as far as creating a custom tune for my 05 Mustang GT 5 Speed?

Its completely Stock with the exception of Ford Racing Stinger Axle Back Mufflers.

Also, if I requested to have my Charge Motion set to a "Permanently Open" state... Would I gain power and not trigger a CEL?

I live in California so I'm limited to using the 91 Octane Performance tune since 91 Octane is the highest level Octane available at the pumps, so any extra HP I could squeeze out of my baby would be greatly appreciated.

should not be a need for a custom tune there really...leaving IMRC open will lose low end torque...

Ok thanks for the reply.

I'm sorry I forgot there is one custom tune need that I need. Could you write a custom tune that will help me with my slow dropping idle/rpm issue? When shifting through gears, let's say on the freeway, third gear to fourth gear the RPMs will drop very very slowly in between shifts and if I don't shift into the next gear up and leave it in neutral the RPMs will stay let's say at 3000 RPM and drop about 100 RPMs per half second and it makes the drivability of the car sort of annoying because rev matching is impossible because the RPMs are way too high for the next gear that I shift up into, it makes shifting sorta "jerky". I've already checked for vacuum leaks and cleaned my throttle body out, nothing has cured it.

I heard adjusting the dashpot settings could possibly cure this slow idle return issue... if there a dashpot setting i could adjust with my predator u7140?
