My 96 with the mods in my sig can pull 20+ on the boost WOT, as for egt's most I have ever seen on mine was 1150 on a long haul up the blue ridge pkway out in WV.... Only time mine smokes is on chilly mornings after sitting all night and only lasts a minute or 2.....

Those boost numbers don't sound right. You should be getting around 18-20 pounds.

I'd pull the intake tubing off the turbo and check the wheel for play or extra oil build-up.

Or you might be having injector problems...

How can i check if i have a bad injector? I will check the wheel on the turbo but what else could cause my problems? Could a weak fuel pump be causing some problems as well?

THere's a easy way to check your fuel pressure... can't remember where though. If it's a bit low you can shim the FPR and it'll boost it a bit.

I have found you can get a better boost reading if your under load. Grab ahold of your neighbor's 15k 5er and see what you have, lol.

Do you have a good connection on the map sensor line where you tied in the boost gauge? I had my little rubber connector go bad (fell apart less than a year old). Amazing the difference when the MAP sees full boost #'s, also a big difference on the gauge.
