Hey guys its been years since I last tuned with the old V1 on the 5.7's and sold everything years ago. last week I bought a 2012 SV6 with the 3.6 SIDI LFX and 6spd manual and thought I would jump on the forum to see if it was supported, from what I can see it is. My question is how much have you all improved driveability in playing with the tune? only owned it 4 days and already done intake and cat back and considering in a reinvestment of EFILive again. Obviously I am a mile out of touch with how far engines have come in these modern vehicles but interested to see what can be done in terms of improving on what it already is.
Keen to hear from someone that has played with this particular engine's cals and your experience in doing so.
TIA
