ZFG 93

Have the ZFG 93 tune. Is this a common problem? How can I fix it?

I have ZFG 93 tune and never had that one. I'd clear it and see if it comes back.

I’ve had a ZFG 93 tune for a couple years. The first week of the tune a guy in an ST wanted to hear my Thermal exhaust. So I hammered it from a light. I got a hesitation and then an overboost code. I cleared it and it never came back in two years.

I agree with the other suggestion to clear it and see how it goes.

I had this happen twice with my ZFG 93 tune. First one I just cleared and didn't think of it. Then happened again. It seemed I was off the line hard on the throttle then abruptly off to compensate for slapping the throttle a bit too much from a stop into a turn to prevent wheel spin or the dynamics control kicking in.

I emailed ZFG with the code description and they sent me a new modified tune to try. Told me no need for data logging unless it happens again. So far so good after that update tune for me.

What were you doing when it threw the code? It’s hard to now why it happened without knowing what was going on when it happened. I’ve had it happen when I hammered it from a traffic light and then let off the throttle when its in the upper RPM range. It doesn’t like that! My 2020 had the VTA valve. Hasn’t happened since installing a BOV.

Pretty much what happened when I threw it twice. My description is just ass. I even asked Adam at ZFG if I should put on a BOV , he didn't say otherwise and just offered the updated tune.
