3900 VVT Performance Options

[Scott205]

Hey guys,

I am looking to see if there are any basic upgrades for power or fuel economy on my van. It has the 3.9L pushrod VVT engine. My wife uses it as a daily driver, and other than a few CAI, I haven't found anything to improve it, not a programmer or anything other than Superchips reprogramming the whole computer.

Any Ideas?

HPTuners should work. It works for an 08 G6 3900. I am currently working on ported head and manifolds, but that isn't anything like programming or CAI.

Thanks Ben, I do see they list the Chevy Uplander (different nose but that is about it) with the 3900. Would you recommend the Standard or Professional model? What else do I need other than a laptop and obd2 cable?

It comes with the cable. You need a laptop or netbook and that is it. The pro version lets you record without a laptop, and you can input a wideband. Cheaper to get it now than upgrade later, but if you don't plan to use a wideband, its not worth the money IMO.

HPTuners support the montana, but not the other vans for the older 3400. They may not support the Saturn even though they support the engine.
