Well I got the itch to work on the ol girl again. I pulled the aih out and cut the inside piece out. Then got to thinking about the threads on the wastegate so I hooked air up and it was opening with less than 10psi so I disconnected the red vacume line. Then I thought about the gpr led thread so I jumped into that. I'm not sure if I did it rite. Its not working. I hooked 1 wire to the post that got hot with the ign and grounded the other. It doesn't work. Sure does look pretty up next to the gauge but its kinda useless at the moment.

Time to go pick the kids up from school. I had to get on it!!!!! This ol girl got side ways!!!!!!! I think that's pretty good when she's turning 38/15.50s

 

Forgot to add before I couldn't get but maybe 10 to 12 psi boost. Now she is getting up around 21psi

 

What other mods do you have? You should fill out your signature so we can see what you've done to the truck. 21psi is good if she's running a stock tune.

 

swap the wires at the LED. It will only work one way

 

I'm posting this from my phone. Everything except what I done today is in my signature.

I will change the wires around when I get home. Thanks mike

 

i swapped the wires around. still nothing. must be a bad led.
