I just picked up a 120a turbo and used it Saturday for the first time in a race.
Very smooth, tons of power. I ran no boost or turbo and still has plenty of power on tap.
My only complaint is that reverse is inconsistent. Sometimes it works, most of the time it doesn't. On the bench, it will work as intended damn near every time. Once on the track and when I need it, it won't work. Tried re-calibrating and it got a little better.
Is that worth trying to send it back for? Probably not. I'll probably play around with it a little bit and see if I can fix it or maybe learn to tolerate it until I can get something to replace it. It's in my racer, so not having reverse is not a huge deal. Practice is going to be a little aggravating.
