1987 non-turbo: 10 deg Before Top Dead Center (BTDC) @700 rpm
1987 Turbo: 10 deg BTDC @650 rpm.
To set the timing, you will need to connect a jumper wire between terminals E1 and TE1 on the diagnostic terminal. This diagnostic terminal is located just aft of the engine compartment fuse box. It is a black plastic box marked "diagnostic" on the cover, which flips open to reveal the terminals inside. There is a diagram on the inside of the cover which explains the terminal positions. On the Turbo model, you need to remove the forward section of the engine cover to gain access to the number one spark plug wire.

The gauge is working fine, the turbo will not kick in untill the engine is spinning fast enough, as the turbo is propelled by exaughst from the engine. So, you can drive around normal and never use the turbo, and climb in the gas and spool the turbo up, what you are noticing is called turbo lag, which is the biggest down fall when compaired to superchargers!

You can get a aftermarket part for your car called a boost controller there are many different types manual and electric, if you go to your local car parts store and ask for a boost controller there is a type called a bleed valve which works by restricting boost to your actuator which controlls the wastegate causing it to open slower than it usually would therefore creating more horsepower... * BE CAREFUL THO AS STANDARD ENGINES, ESPECIALLY OLDER ONES CANNOT HANDLE MUCH MORE HP THAN THE FACTORY SETTINGS *

Testimonial: "Exactly what I needed to know."
SOURCE: What feeds the boost gauge?
The boost gauge is fed by the Turbo. It tells you how much extra air the turbo is putting into your engine. This is turbo ONLY. Usually a little plastic line from the turbo to the gauge.
