Where is my power going?
 

I have a 1990 turbo sport top and it is making boost, is perfectly in tune, all cylinders have near new compression, has a newly rebuilt automatic transmission, just installed a new K&N cold air intake and it just doesn't put the power to the wheels when you stomp on it. It sounds great and looks nice but is way to slow. What am I missing? It ran almost exactly the same before I did all the stuff I listed above.

split hose/broken vacuum line will completely ruin your boost pressure. Other then that it may be a computer problem but not likely. Also stock supras don't have ALOT of juice unless you crank up the boost, maybe look into a boost controller.
