No box = limp mode?

[GFB]

Pulled the adrenaline to send off for firmware update. I expected a CEL, but wow the truck feels worse than driving a chevette. Is this what they call "limp mode?" I'm too lazy and it's too cold out to put the harness back to how it should be. Surely it'll be ok to drive for a week like this, right?

I don't think you should be in a "limp" mode.

But, you probably will have overboost codes if you don't have a boost fooler...

It would cut fuel once you clear 22 psi of boost, and probably wouldn't be much fun to drive at all.

all you have to do is disconnect the adr harness from the map sensor and reconnect the stock harness to the map.

right now id be surprised if your making 8psi

If I keep the pedal to the floor until 3000 rpm I can see 20psi lol.

Plug the stock MAP sensor back in and you'll be fine. And yes the truck feels like a dog without a fueling box, your missing 100+hp LOL.

Your fuel milage will be horrible if you don't plug the wiring harness back up.
