truck cuts out on setting 4

[lb7lbz]

hey all, was playin around on some back roads the other day,getting ready to go to the dragstrip next week.my problem is when i stay on it too long it cuts out.truck is an 01 lb7 with the following mods,diablosport predator,mbrp4 inch exhaust,kennedy boost valve.modified stock intake w k&n drop in.predator is on setting 4- 85 horse mode. egts are within spec. under 1300 degrees boost is around 30 psi. i sometimes get a ses for high boost. i was under the impression 30 psi was ok,is it the boost that is making this happen?

2001 programming has issues when it comes to boost codes. Get your ECM reflashed with 2002 programming. Some dealerships will do it. JK can do it, I would recommend getting his basic tow/economy tune on top of 2002 programming as a baseline for any LB7 truck, the programming is way better than stock, my 2002 oil stays translucent between changes - its such a clean burning tune. Have you seen a diesel that does that?

I have a 2001 core that could be re-flashed. Let me know if you are interested in it - $150.
