I,m only getting about 18 pounds, is this typical or do I have a problem somewhere? Any ideas? Thanks.

 

Sounds about Stock to me!

 

What exactly does "pump tweaked" mean?

 

My 92 4x4 with the auto and the 21cm turbo housing will only boost 19/21 under a big load full throttle. The 93 with the 5sp and the 18.5cm turbo housing will boost 34/36. So your probably not far off on your boost. Check your hump hoses, connections, and the i/c. You may have a leak that's losing a lil of your boost pressure.

 

Thanks Smoke I will

 

It was turned up by Northwest Fuel Injection a long time ago. But thats the only details i was told when bought.
