but when driving kinda hard, my car hesitates for a second or so when I change from 2nd to 3rd, kind of like its hitting a limiter of some sort, at first I thought it was hitting a boost/fuel type cut, but it does it before boost builds up that high.
I really dont know how to describe it any better, just flooring it in 2nd then quickly shifting to 3rd leads to it losing all power for a bit, lifting off the accelerator then putting it down a bit more gradually seems to sort it, but that doesnt really help with my times at the track

could it be ignition related?
