How much 0 to 60 improvement?

[jc522]

I'm tempted to install a JB4 on my 2021 TTS. Seat of the pants testimony and dyno sheets all speak highly of the product, but I'd be more convinced if I could see what kind of 0 to 60 performance improvement I could expect. I'm surprised that I can't find any discussion of that. It is easy to measure with Dragy or a G-Tech performance meter, and I expected that people would routinely keep a log of peformance gains after various mods, including the JB4. If anyone measured their actual JB4 performance improvement, please post the results.


No answers. No measurements. Wow. Expectation Bias run amok?

George? Terry? Anyone?
