    I wonder if traction control will be an option that you have to pay for, and how much it will cost. Every race team that I know of that's added TC to their ECU, has gone through nearly a season of trial and error to get it comparable to what a driver can do with their right foot. (In the dry)

    Definitely a good feature, but it's not as simple as the ECU manufacturers seem to make you think. There are multiple torque control strategies that may work well on an N/A engine, but poorly on a Turbo engine.

    The TT Stage 1 is certainly making some torque down low though....I bet it's going to be a blast to drive on the street!

    Yes, but why? Traction control = cutting fuel injection and timing = less power = why be able to make the power if you're going to cut it?

    A lot of people don't realize that low low torque results in harder conditions for the motor. Oil pressure is RPM dependent - start pushing down on the pistons super hard when the oil pressure isn't so high (lower RPM torque curve) and things don't last as long.

    Looks good but I feel it falls off way too much - would have probably preferred GT25 - GT28's personally.

    Absolutely - even looking at the settings lets you know how daunting getting TC setup correctly is. Remember though that most of these aftermarket companies are using the TC for linear acceleration. When you want TC in turns is when it gets real challenging to configure.

    That would be a nice amount of lag tho. I think they were trying to stay away from that type of power curve. I can just imagine two 2871's... BEAST.

    What's stage 2? Twin GT25's??? Looks like you're going to need more power to keep the RHD boys happy.

    Let them get stage I out first and see what the demand is like. This is going to be a smaller market.

    It looks like they are either shutting the runs down around 6k or these things just can't keep up that high. The runs stop right after torque and HP intersect. It's a little hard to tell since they scaled the dynos on MPH instead of RPM for some very strange reason.

    I would prefer RPM as well but you still get a nice comparison.
