I have zero experience with 3.5's, but start with the basics like:

- VE (*if* it does your car good)
- MAF
- remove anything that disables the inectors when you don't want them

- For a little more MPG, try getting the tranny to shift a little sooner and the TC to lock up a little sooner.

- Increasing timing anywhere from 3-6 degrees over stock will help.

- Cold air intake will help.

- Decrease exhaust restrictions

- Increase the TP needed to activate PE mode by 5-10%

Then there is some of the obvious stuff... driving technique, tire pressure, no jack-rabbit starts, using the narrower tires over wide and sticky ones.

That should give you a good start.

I didn't think the 04-06 Malibu 3500 was supported...did something change recently to allow that? If so, I need to save for some more credits....

3.4 sorry

Well, that sucks...for me anyways. I don't understand how every motor in the past generation Malibu is supported except the 3500 non-vvt...which happens to be the bulk of the motors that are in these cars.

I Know We Got A Malibu Maxx 3.5 As Well.. Wish I Could Mess With It.
