It might be possible to do 3bar for $9.99 each if you don't mind a little soldering and glueing on some stock ones.

I'm not sure if the above is the exact right one but measurements could be taken. The output would be 0-5V no matter how many bar the sensor is. Therefore, you could use, say, a 5bar unit if you wanted to, but the resolution would be half of the 2.5bar unit.

You might ask the seller on cobalt ss to see if it comes with the orings. From the looks on the picture......it looks like it doesn't. The orings come in seperate packages if you buy "the kit"


If you want to buy everything seperate (Sensors & both O-rings)...you can through CED

im going to see how much they are at work and at bennit, i mean when you get the GMTU all you are really paying for is the code for the tune. if i get the sensors i can just load my own tune. right??

Turbo Hearse

Yup

O rings can be had at most parts stores for pennies

ChevyGuySS

i think im going to get these sensors and the harness adaptor from crate engine depot and make my own tune

Turbo Hearse

that's the smarter thing to do. The gms1 is a canned tune that doesn't really do a whole lot. You're already tuned. This will just allow you to read past 22~psi

Already made changes to your tune just waiting for you to get the sensors.

thanks rob, oh and ive notived that with my dp open it only boosts to 20 psi while with it closed its 22 or 24, i forget what we set it at.
