In the required fiel, I've put 306, 80 lbs and 14.7. Only thing that might be different is fuel pressure. injectors are rated at 43.5 psi and now its set at 40 psi. I dont think that will make significant change to the tune (5%ishh) Could you walk me throught what's wrong? Here's the tune that has been changed by Live Analyze. There is a lot left to do.
In the datalog yesterday, I have seen voltage spike to 21v a split second, I guess that dont help too.

11 to 40, 10 to 16, 9 to 60, 8 to 46 and 7 to 20. I have battery to the trunk.
One negative 2 Ga wire 2 feet away on the Chassis in the trunk One negative 0 Ga wire rear to front on the chassis, driver side. On that point, one 4 Ga on the timing cover. The other one goes on the ECU stock ring ground screw on the chassis in the fenderwell.
Ground firewall to driver head and ground passenger chassis to the other side of the timing cover. ECU is also grounded in the kick panel.
I found today the cause of the voltage fluctuation. It's when my wideband is connected. I've connected it directly to the battery for testing and the problem still there. I'm still looking how to fix this issue but the good new is, now I know where to look at.
AEM 30-4100. When I hook up the ground of the wideband directly to the battery, I still have the problem. When I put the positive of the wideband directly on the battery, the problem disappear. So basically, there is a feedback from the positive that I dont understand. Still looking for.
Would you like to verify my tune because I dont understand why I have up and down when starting the engine. Is there some setting I could change to make it start faster / better. Would you tell me why I have high VE number in that tune ? The AFR look almost right now. I will have to trim some cell but generally speaking, its ok. Thanks.
