     Also, i tried the Gtech and my 0-60 time came out 7.27 sec. 
     my buddy with the M conv pulled a 7.3  After that, my other friend in 
     a cavalier pulled a 6.5 and both of us can very well beat the chevy.
     what could be the problem here?

     Well Franklin, while not totally accurate the G-Tech isn't bad for 
     what it is.  So lets take some guesses.
     
     1. The entered weight for one or both cars is not correct.
     
     2. The G-Tech is not mounted level.  
     
     3. Did you run both cars over the same stretch of road?  ie Did one 
     run slightly uphill/downhill compared to the other?  Or worse yet, one 
     ran uphill and one downhill?  There are very few level roads.
     
     4. Somebody was having a great/horrible launch?
     
     So, go to a stone dealer etc. and hve the car weighed before your 
     runs.  Make slight corrections (7-8lbs) for each gallon of gas 
     used/added after the measurement.  Mount the G-tech as level as 
     possible.  The manual tells how to check it.  Run both cars over the 
     same stretch of road.  Try to make consistent launches.
