Default Anything to be gained from Dyno tuning?

Has anyone here ever had their car Dyno tuned? If so, was there any gain from the session? How does Pontiac have the A/F setup on these cars?
If anybody has any runs mapped out, please post.
Thanks.

without any modifications, there is no tuning to be done. Dyno tuning typically comes with modified cars with computers that can have adjustments on the fly, or using a manual Air/Fuel Management system. And, Yes, if you have modifications, dyno tuning will definately make a difference

I've seen on the new GTO'* they have gotten 15-20 HP just from remapping the fuel injection system and doing things like disabling torque management. None of this applies to the Bonneville?

yes it does, but you need to modify the computer to do so, or use a programmer while on the dyno...

I don't know if anybody here has tried dyno tuning a stock Northstar. If you're willing to spend the money and be the guinea pig, we would all love to see your findings. Just make sure you find a reputable aftermarket company that has experience tuning the Northstar. You don't want any old Joe Schmoe screwing with your computer.

Ryan of GMtuners, when doing the final tuning for my */c LN3 connected his scanner to my car and we did some WOT runs. I would say that with pretty much stock motors, there'* not much to be gained. There'* performance programs out there already...no need to pay for the dyno time.

Not for the Northstar. The code hasn't been cracked or even attempted yet.

I wouldn't say there would not be gains in a tune with a stock Bonne. The gains would be more if the car was not stock though. I've seen personally (my buddies Cobra) almost 50 WHP on a stock Cobra with just a tune. Also on a tune (even stock) you can improve your MPG drastically.
