Okay so i saw the other thread and it kind reminded me i want to ask a similar question, just didnt want to high jack.

What happens with de-fueling, how does it feel, because pulling a trailer up cuesta grade i can easily hit 26 psi with my truck? but maybe cause i dont exactly know if it is doing this or not, i havent realized what i am looking for. maybe i should just a boost fooler and see if it is any different. it has only thrown the over boost code once that i have seen.

when mine did it you can tell you lose power and your boost gague just drops because the computer is cutting the fuel down....

Usually it feels like it falls on it's face(noses over) and/or you might notice the boost drop some.

If your not running any kind of programmer or chip/tunes I don't think it will be very noticable for you.

it can be, like if you hit the revlimiter ..like acidentally forgetting the od button is off when passing ....that sucks. I don't stay on my boost long enough to defuel much. due to that.

alright thanks. maybe it is cause i dont have any sort of chip or programmer, but i can hit 26 psi and hold it all the way to the top of cuesta grade pulling a trailer. that is why i was curious, cause i thought most said it would kick in and de-fuel before this point.

Dunno for sure, but i ordered a overboost annihilator and it will be here tomorrow, so i will install it when i get my truck back this weekend. it is getting a new HD tranny!
