Having put 312,000klm on my 08 3.8L Auto the best performance mod you can do is first regear and then reprogram with a tuner.
The sluggish response of the 3.8 is attributed to very poor gearing right from the factory.
For comparison a 3.8L Auto with 4.10 gears is equivalent of a 3.6L Auto with 3.21 ..
I ran 5.38 gears with an Auto on 37s and it was not gutless.
