    Its a really noticeable difference. No dyno need. It has more power right where it need it. Any power increase in this mutt is very noticeable.

    You know how if you floor a G2 it kinda just hits a plateau where the engine keeps revving and your not going any faster. Engine is screaming and your really not going any faster.

    Now its keep accelerating. To a point where you can rev past where you could before so you have to watch that lol.

    My car is an exception though. band new battery and engine in really good shape. I highly do not recommend it if the engine is tired is making noises is eating oil and if the battery is old. All you will do is blow your car up becasue you will be driving it harder.

    I don't know how that applies to a gen3. In my gen3 the engine will rev to 5200 rpm no problem. It will only do so when you're going fast enough, the way the HSD is laid out it will not rev to 5200 rpm when you're doing 30 mph.
    My car accelerates no problem right until the speed is limited. This more sounds like snake oil.

    Never mentioned a G3. This a G2 under power phenomenon. G3 is a much more powerful car which would probably still respond very well to this device. But you have to understand the VVT system to understand that.

    While, at the same time, understanding the VVT system is no guarantee that you'll understand that.

    For those that have the OBD dongle, the Car Scanner app will measure 0-60 and 1/4 mile times. That way you don’t have to measure gains by the butt-dyno. LoL

    Butt-dyno readings in my car are heavily affected by ambient temperature and battery SoC; I would hope that any app intended to document performance is also logging those, as well as pedal angle, and of course it would have the opportunity to log a lot of torque and power readings available in the HV ECU.

    Sure. But this is the Gen3 section so posting it here would mean that it applies to it too.

    Any update from anyone with a red bullet in a gen 3? I’m thinking about getting one myself, but would like to hear from other gen 3 drivers if it is a noticeable difference. Awesome to hear OP had a good experience.

    There has got to be a reason Toyota didn’t make the stock like the red bullet.

    Well… they don’t come with performance exhaust nor a cai either. But I would imagine it affects your mileage as you will be on the throttle more as it’s fun to have more power.

    The claim made for this product has consistently been:

    • (a) it makes valve timing changes happen faster than with the stock valve, and
    • (b) because of (a), happy things with performance and drivability ensue.

    Last Wednesday, mr_guy_mann put up the first (known to me) direct test of whether (a) happens. The test was done by scoping the crankshaft and camshaft sensors, which had already been identified two years earlier as the way it would have to be done. Data from OBD-II would not suit the purpose because of the delays in polling OBD-II and getting replies.

    The work does have (for now) one methodological weakness, small sample size; it was well designed in taking multiple runs with each type of valve, but having purchased only one sample of each type, it cannot (by itself) rule out whether the single sample of any of the valve types was a dud. But it is a very good start on getting some basic information about this product that has been overdue for a couple years now.
