The gearing will most certainly have something to do with measured rear-wheel HP numbers (more specifically: torque numbers). It's why manual transmission dyno runs are usually done in 4th gear, which is almost always a 1:1 ratio. In the case of the V's auto, it's a 1.15:1 ratio.

^ gotcha. I'd still like to know the mileage #'s as more than one member has mentioned the car really opening up after a few hundred miles.

Last Q. Who makes the ECU unit?

Cheers

A1: We will be changing more parts on the new V, including adding boost.

A2: We are currently looking into what modifications will be necessary to handle any given amount of added power. We want our parts to not only produce more power, but produce more RELIABLE power.

A3: In this current configuration we ONLY added the ECU box with revised tune. NO other modifications were made.

A4: We make the ECU box. It is a plug n play box similar to the ones we sell/produce for the STS-V and XLR-V.

Thank you.

ECU box = MAF translator?

I suppose that's one way to describe it. It's a plug n play box that connects in line with the MAF and loads its tune in there. It is only active when plugged in and once removed, the vehicle returns to factory settings making it a little more user friendly and dealership friendly.

I don't think this is correct.

They can do a dyno run in first gear, as long as the dyno was adjusted for it.

This is what I was told though---I make no claims to its accuracy.

Any info on this?

Is that invitation open to anyone?

Do you have your own dyno Jesse?
