I am just getting going on a 08 G8 tune, car has a Livernois stage 1 cam, kooks 1 7/8", Fast 102 w/102mm tb and 100mm maf. I just finished up with the MAF tuning when I noticed an intermittently funky idle surge. I attached a tune along with a scan and histogram. I am sure others have run into this. Let me know your thoughts, thanks in advance!
Edit- Just spent some more time searching and think I found a solution. Please delete thread, thanks!
2nd Edit - Car is not yet fixed, still a work in progress, I will post up a tune, hist, and log when I get back to the cities.
