Hello everyone.
Looking into performance parts and things I could add to my 2009 G6 GT.
Already in the process of getting a crabs intake and gonna work on a GT-R exhaust next.
I was looking at the wams 2007+ G6/Malibu/Aura 3.5 Performance Tune.

I have a few questions about it. What does it do, is it easy to install? and how much HP/Torque is it going to give?

Most of the tune is from changing the acceptance of octane levels and shifting points. A change from 87 to 91 octane will provide a 10HP increase. Tuning a 87 octane wouldn't be worth it.

Is it better to get a new ecm/tcm and keep your old one or just send the old in

If the 6 is still under warranty, you should keep the OEM unit to put back in for warranty claims.
You can always sell the tuned unit and get your money back if you sell the 6.

CRAB's won't void that warranty, but a tune will.

Yes i recommend you get an extra PCM.
I did. now I can swap it at will.

I TOTALLY recommend Chris's tune. It woke up my G6!

Also yes you can sell it but it cant be reused without a rewrite on the tune to match the vin number so it can talk to the BCM/TCM correctly.

I just read that the GT-R is currently sold out so if you go that route get on the list NOW.
Your tune will be better if they know you have an intake so you have to tell them that
you do. So if you get the tune before the intake hold off on the tune install (you will run lean) without the intake on. Clear as mud I know.... lol

So your saying if i got the tune before i got the intake..then got the intake the car would run lean. So its better just to get the tune after i get the intake

Do all the engine modifications before you get the tune. I have the intake and plan on getting the GT-R (on the list now) before I get the tune. That way WAMS can compensate for those when they tune the settings. The intakes and exhaust really affect the optimal settings.

Yes. It is specific to your engine size and year and maybe transmission type.

Any educated guesses where I would be sitting HP wise on my GXP with the WAMS on top of the Crabs? (I would say plugs, but I doubt they do much besides throttle response)

93 Octane tune with Crabs would increase the HP by 20 I would estimate at the most.
