This is the hesitation that typically happens when you get on throttle after braking through a turn, of when tying to pass someone on a freeway. You mash the pedal, and nothing happens for maybe as long as two seconds. I've done a lot of searching lately because the hesitation is really getting on my nerves, but have not been able to find any definitive conclusions on this. Over the years, people have thought it was coil packs, turbo lag, and maybe a few other things. I've ruled all of these out on my car. The most plausible theory I have come across is that the "learned" driving habit, affecting the engine and transmission programs may be the culprit. That is if you drive normally, you will have this hesitation. On my 2006 CTT, one thing I do know is if I disable the PSM, the hesitation is gone, but the shift points go to higher RPMs, and the car all around seems more high-strung. So, the hesitation is gone, but it's not as relaxing to drive. I have heard that the normal, PSM "ON" mode hesitation can be fixed by running with PSM off for days or weeks, tricking the engine management system into thinking that's how you really drive. I may try that, but I would guess that over time back on in the PSM mode, it would revert to the original "learned" driving habit, and I was wondering whether there is any other more permanent solution out there. Other than the device (forget the name) that tricks the gas pedal position sensor into thinking the pedal is further down than it is. That seems like another band-aid to me. If anyone else is well aware of this phenomenon, is there some reason understood for why Porsche programmed it this way? Only thing I can think of is they did not want people hitting the throttle hard, coming out of a turn in a 5200 pound vehicle. But what about the detriment and danger when attempting to pass on a highway? Thanks.
