I'm not able to look at my tune file right now, but going by memory it's in the transmission side of the tune, and it may be labeled BTM. It should have an RPM window that you can change the number in. It basically makes the truck start pulling fuel, timing, or both to keep you from standing on the gas while the brakes are being applied. This used to keep me from brake boosting past about 1800 RPM.

I was WOT in 1st gear and 4wd. It wont rev past 2200 and kinda studders there which is only 5psi. Anything in particular causing this? What do you guys think.

the studder not sure, but if you remove it, you probably will still be at that psi/rpm... The convertor will stop you from going higher, unless you can add a freakish amount of more power.
Now wheres the rest of the video were you dump the brake and get it.?

I never could get mine to brake stall any boost. As soon as it hit .5 psi i started pushing through my brakes and that was with a 2800 stall. I would be happy with 5 psi all day long especially on a stock converter.

jacks if your heading down to leicester tonight try to build a couple #'s in 2wd, im sure you will trap 100 since we both trapped same speed even if mine was 1/2 second slower with no brake boost.
