The next big mod?
OK guys, i know everyone knows about the 10k mod, as i have.
Blah blah blah, tricks computer, blah blah, more fuel blah.
Now, looking under the hood, "hanging" near the AC hoses going into the cab, on the passenger side, theres a little black box, with a hose that goes to the manifold. This is where my boosts guage is tapped.
Undoubtedly this is a MAP sensor, or equivelent. This is the little ******* that tells the computer how much boost there is.
My question is, could you put a resistor there instead of the sensor, so the computer always see's, say 24LB of boost?
Even if you hit 30psi, the computer would never see it!
If you mashed the pedal, the truck would over-fuel, just like a chip, and make some serious take off power...
This little sensor couldnt be to complex, theres only 3 wires!!!
Anyone ever heard of this?
A 10k mod and this, would be awesome for 1$ of parts...

that is the map sensor..if it see any thing over 22 it will tell the pcm to start defueling..OBA lets the map see 22 and thats it..even if you fit 50.

if that is what you are seeing.. the pic below you can see the map sensor to the left..the OBA looks like a dial sitting on top of the map sensor and has 2 red hoses..one going to the spider other to the map sensor..whats good about this OBA is does not leak boost at all..it just hides it from the map sensor..

The mechanical regulators most people used don't have that problem.
