I tried to find my max mph, and the needle just touches at 100mph, but never goes to 0. Going to 0 means you're doing at least 105 mph. My only code is the P1211. I'm also thinking the speed limitor is still there with the Predator installed and causing the defueling. My Predator is set to 100hp.
Good luck with your explorations, and looking forward to your results.

i run the diablo predator also, and i can't turn off my speed limiter... when i get a cust chip from jody... there won't be a speed regulator on ANY of my settings, unless of course i get a "de-tune" setting for the rare occasions when the wife drives my truck..!

For those looking into a Boost eliminator, really need to look at our DRV++. We have done extensive testing on these and offer a life time warranty. Read the Q&A section on why this works the best. We have not had one fail so far, and have many happy customers.

The blowoff valve type didn't work for me, and still tripped the EBP code, and sometime the high boost code.

I have the single boost relief valve,, i think i got it from Black cloud diesel a year or so ago. I can still set the overboost\SES light. Have tried adjusting it up and down and no change. At the time everyone said that(BRV) would fix it. Not sure if I am not adjusting it right or what,, I have screwed it all the way in and almost backed it all the way out and it still trips the light. Even now with no tuner\chip if i really stand on it about the time it shifts into OD the light comes on, and thats right at 25lbs of boost.Before with the tuner about half throttle it would throw the light everytime. Maybe I dont have it adjusted right? or maybe i should have bought the regulator type instead of the bleeder valve style?

Can't wait for you to get the chip. I'd like to hear the difference between the Predator and chip. Maybe you can still keep the Predator installed. The chip overrides the tuner. So when you go to the stock setting, that will be the Predator tune. They even have a setting, where you can let it idle, but won't drive so you can fill up the gas with the engine on without any worries about someone taking off in your truck. Also a high idle setting for cold weather.

I don't think there will be any comparrison between the Predator and the chip. I know for me, with the other 2 I ran in the past, they were nowhere near my twildman chip. It was like a night and day difference.

Also I still have powdered metal rods since my truck is a 2002. One reason I'm afraid of getting a chip.
