Ok so I did some head scratching and with my cam I should be aiming for between +1 to +1.5 to fix the Injection timing issue with a max of +2. Stock is 6 so 6/24*360. My exaust valve closes roughly around 25 degrees later than stock so 1/24*360=15 intake duration is no issue here you could probably add 2 or atleast 1.5 and that should solve the issue. I'll be testing this as soon as weather permits
