Current Throttle Controller Options?

[why?]

Try a throttle controller first. Sprint is good name and so is Weapon R. I've never heard of pivot and I would stay far away from generic ebay anything, especially electronics.

And honestly going to the 1zz throttle body should be one of the last mods you do. There are so many things that are better and easier to deal with before you make that swap. If you are looking for more responsiveness after the boost controller there are a few options. Since you said you have an automatic I'd try pulley's and lighter wheels and tires first after the booster.

I hate the Yaris throttle settings and I really should try a good booster, the blitz had a ton of settings so of course I missed it. At this point though not sure I want to spend the money.
