I have a 5,3 ls9 cam .020 dished Pistons stock crank and gen 4 rods. 799 heads. Ls6 intake 78/76 on3 turbo. I've changed the timing map numerous times. And I've been having an issue with it cutting out and breaking up while in boost. I've been trying to research this for a week and a half now. And I'm not getting any luck. I changed it, the. Pull the data log and it's showing still above 35* of timing. I'm only running a max of 15 pounds. Nothing in my timing map is over 22*. I'm getting frustrated and pissed. I should also add that I'm ver new to this. So dumb simple explanations would be perfect. Thank you in advance

What are the timing modifiers set to?

Ones coolant temp and it doesn't pull time till 220 and goes -2. The other is manifold air temp and that one pulls timing at 128* and that starts at -1 to -7 at 254.

You have to host the file on a file sharing service and post the link.

Is it hitting a fail safe in the tune? I had a similar issue. My fail safe was set to cut timing at 9 psi in the boost control configuration. As soon as it hit 9.1 psi the car nosed over and ran like ****. It would take a few seconds to "recover" and would run fine until the boost limit was reached again.

I thought that so I changed it to revert to wastegate. still does it. also once it gets hot it keeps dying. I changed the tune last sunday and went out and drove it. got on it once in second it nosed over then about a mile and a half down the road it died. pulled over restarted. drove about another mile then died. then it kept dying ebout ever20-30 feet. had to get it towed home and haven't touched it. I have no idea whats going on. hopfully I can look at it this weekend. was told to check the crank sensor readings for the stalling and spark plug gap for the break up. I hope its that simple. ive been dealing with issues all summer. I'm in buffalo so my warm weather is gonna be going away soon. lol
