I have some ????????

Maybe I'm just being over concerned but I noticed the other day that when I have A/C going I'm getting a knocking sound, but when I shut the A/C off it goes away! I just had a 203 thermostate put in along with some guages! O hope I'm not being perioned! Is it supposed to do that or is something wrong!!

One more question, What should be a normal reading for your pyro when it is located post turbo, and how many psi should your boost read when say your cruising about 70 mph. thank you!!!!

I do not know about the knocking sound. Maybe someone else will know.

As for the EGT and boost numbers....in the stock tune at 70 mph on flat ground I will see about 750 to 800* EGTs and 6-7 pounds of boost.

Are you sure it is not the compressor clutck clicking on and off every 10-20 seconds?

For the temp, you should see no more than 600-700 post turbo, and 4-6psi of boost.

i belive that is what is, but I just wanted to be sure that it wasn't going to go out on me. It seems to be a little more louder, but it quits when I shut the A/C off! My temp for my pyro has only gotten as high as 600 degrees. The guys that installed it sayed I shouldn't goo over 1200 degrees.

It sounds to me from what the "guys" said.. your pyro is pre turbo.. If you are post turbo and get a temp reading of 1200 degrees, i believe you are going to melt something.. Can you tell us where they installed the probe?

it's on the down tube right behind the turbo! I thought if it was in the down tube you should add a couple hundred degrees versis having it in the manifold!
