help please

sorry but I just put 3inch on my 93 ty and the boost gauge read 2lbs and stoped working, the turbo is not building boost. Is there a boost cut, or should I reset the computer. I did not gut the cat so i dont why it is hitting 2olbs on a stock turbo and stock chip. Did I blow my turbo or do i just need to disconect my battery to reset my ecu. Thanks

Check all vacuum lines.

2 psi or 20 psi?

Check your vacuum lines and check for trouble codes.

It hit 20psi

thanks

All vacuum lines on or near the wastegate and boost solenoid. I was boosting at weird levels until I replaced them. Replace them all with silicon vacuum line if you can.

massive overboost will happen in this way if you remove the vacuum line on the boost selenoind that goes to the WG. The turbo spools freely doing this. Its a good way to determine if you are having WG problems or if its sticky.

so...the point is, you are having similar problems just not all out...so you likely have a vacuum leak on that line. If its stock, then it could be the elbows on them or the line itself.

like suggested, replace all the vacuum lines anyway...its a common problem with the age of these trucks.

oK i also want to install a mbc so I can turn the boost down, it is a simple boost controller just need a link on how to install on typhoon or instructions.

Thanks again for all the help, I will let you know when i find the leak

Does your new exhaust have a cat? I know you can get overboost like you are experiencing if you remove or gut your cat. Since the only thing you changed was the exhaust this is the first thing that comes to mind. If its catless then you might have to adjust the wastegate rod to alow less boost.

The cat is factory and I am not going to replace it untill I get a custom chip.

I found the leak, the ic cooler box was blown off of the intake the silicone was awrped, what i am thinking is that once I saw 20psi and let off the gas the tremendus pressure went through the hardpipe and blew of the ic box. I think that a BOV would have helped this. But anyway for now I need to know how to hook up the manual boost controler i have for it, wastegate and what vaccum source?

Also I was involved in a hit and run tonight so now I need a new grill, front bumper, side marker fog light and blinker, + a new headlight.

Where can i find a grill and front bumper or cladding for theese trucks?

Thanks again.
