the performance is ok but everyone else on this forum says they can spin tires and i don't see this kind of torque at all and i have the supercharger. The spinning of tires is the only way i would know how to test torque. Should i be able to spin tires in a 95 ssei supercharged from a complete stop going straight?

uh yeah.

how long does it take you to get to lets say 60mph or so?


How many miles per tank are you getting?

Fill up the tank.

Reset the trip odometer.

Drive for several days.

Fill up the tank.

Divide the trip odometer reading by the number of gallons you put in, that is your MPG.

Do it with mostly city driving, and try it with mostly highway driving.

See what you get.

Reset the trip meter, drive the car for 100 miles or so then fill the tank again the same way. Don't "top off" the tank, just fill it until the pump kicks off and that is it.

Now take the miles traveled on the trip meter and devide that by the gallons used (the gallons you just put into your tank). Example....134 miles traveled devided by 6 gallons of gas = 22.3333333 miles per gallon.

LOL, one step at a time there buddy. I'm not saying you have a bad sender, I'm just saying it is possible.

Step one, check your gas milage the old fashion way....as stated in the last few threads.

What does your boost guage read at full throttle? Like from 20 mph if you step it to the floor and hold it there until 60 mph how high does the PSI get?
