I've owned a 2014 XTS V-Sport (LF3) for about 2 years now and after my first time taking it to the track last weekend I've decided to try to tackle tuning it with the primary goal of being able to hold 15-18 psi boost at a more constant rate than the stock variable 12-15 psi, and to actually learn about and understand what I am doing along the way while keeping my chances of catastrophic failure to a minimum.
I've parsed a few threads here on the LF3/LF4 platforms and have already gleaned some good information. At this point I am wanting to start with the basics of eliminating KR (of which there is a horrible amount in the stock tune), getting LTFT/STFT's dialed in, and tuning the MAF's.
As earlier stated, my experience is limited to GEN III V8; how much of that tuning process translates over to the LF3/4 platform? I've already begun the process of eliminating KR but not sure if some of what I am seeing at heavy acceleration and WOT is TCS related or not.
Attached is a log of mixed driving on the stock tune, and my current tune that is my first attempt at getting rid of the KR observed in the log.
Any pointers on where to start or reading recommendations are greatly appreciated.
