I bought a 99 s80 t-6 for 9000 with 92000 miles, because the price was low i expected there to be some problems but while i am getting the car fixed i find out that the car has been in an accident,is there anyway to tell that i am getting maximum performance out of my car??

 

Yeah there is.

1. Search for what your Hp and Torque figures are suppose to be STOCK.

2. Once you find these numbers have your car dynoed. More then likely since your car is an automatic your going to see a loss of 25% due to the drivetrain being automatic.

3. If you want to know your boosting correctly, go to http://www.egauges.com , and buy an Autometer boost/vac gauge. Have it hooked up and see what your boosting.
