1988 turbo issues

Also I figured out why my pyro wasnt working someone didnt know what they was doing and put the red wire to a bolt holding the gauge in the cluster and the yellow to one terminal and took a random wire over from another gauge I have no idea if it was ground or positive so I rewired it correctly and the gauge doesn't move so now I am just going to order a new one with lead and probe and be done with it I found a isspro gauge I liked that has boost and pyro how much psi should I be? its a isspro r609

 

Ok sorry for the extreme delay in replying I took so acetone today and rubbed the paint off and took a picture of the code hopefully this is what you guys needed also installed the new pyro gauge and probe today.

 

Here is the picture
