Ok guys so I got this mailorder tune and It kept throwing a code. P0300 general misfire. Well I got my HPtunes and now and I tried a BUNCH of stuff to make it go away. I bumped the MAF setting up 1.15 and still nothing. I just set my timing retarded across the board. It is now lower than the stock timing. I did some loging and I noticed NO knock. What can be done to fix this? Below I added the tune I got from the mailorder place, what I tried to fix, and the log I did.
