Ive had the same exact issues with mine. Ive posted questions but never really had an explanation for it. "Grizzlyoffroad" posted a question just like this weeks ago and still hasnt got an answer.

Welcome to the club bud! We've got jackets.

i dont know what could be wrong. When mine went into limp mode i never had to reprogram the computer. It just cut off all power for like 3-4 seconds then it surged back and was fine after that. It was also while doing a burnout. I havnt experienced that when driving or passing. Ive also pulled my ...

thanks for the response. no engine power loss here.

I just installed the diablosport programmer on an 07 chevrolet classic with the 5.3L engine. After tuning we get a "reduced engine power" message on the cluster. Why is that and do u have an update for this vehicle? The part # for this programmer is U7192.

well i tried it and it runs awsome, provided that i dont burnout. But the acceleration is incredible. Ive been running it on the 120hp setting for about 4 days with no problems. And the smoke coming out the stacks looks really cool when accelerating.

Oh i see. Thanks dobert. I guess i can try the higher setting now.

This seems to happen when I try and do a burnout. The wheels start to spin then the truck just bogs down to where the tires dont spin no more( as if it shifted from 1st all the way to 5th or 6th). Shortly after that the truck gets power again and hauls. But that is a loss of about 2 to 3 seconds. Is ...

Is there any way i can use my predator to disable the limp mode on the Allison transmission?

Thanks alot bud. I will try that and see what happens.

Does using the tow/haul button like that hurt the truck at all? or r u just using that whenever u r using the 120 hp setting?

No respond on the ABS issue?

so....what do you suggest i do?

the latest revision i have would be the r20. Just downloaded it last week. Should i dowload it again?

Im having a similar proplem with my allison equipped 07' duramax. I cant do a burnout without the transmission bogging down or it might be fuel related too. But all of a sudden there is a lack of power and then the itll haul. It is really annoying and would like to know if there is a way to stop it ...
