Guy same truck new issue. Okay 430++ CI with 15-16 PSI Procharger. This is running the 4L80e that we just figured out. The truck starts, runs , drives great but when I go WOT something is happening with the fuel.
If I go from a dead stop the AF goes to the roof and you can see it on the WB and the 02 Voltage hits the floor. In the log I stayed in it alittle longer for you guys to see.
Now if I go from a 20mph roll it will pin you back in the seat like a rocket. AWD is fun when its working right.
I had 96psi at 4 bar injectors I went to a 1000cc inj and set the fuel PSI at 3 bar and still no luck.
I have tried everything I can think of. Truck runs twin 340's in the tank. I verify both are working and I did a run to verify fuel PSI is good. Everything checks out.
Any IDEAS
Its obviously SD with a 3bar senson on a E67.
What can pull fuel like that from the inj??? I have all TQ setting maxed or turned off. Is there anything in the trans tune that can affect fuel like this???
Any Help would be great guys.
Thanks for all you do.
