UPDATE: The same test car with 96 MON (100 r+M/2) fuel at the same boost settings as tested with the Torco pulled much less timing with the 96 MON then the Torco, so the results are: 91 r+m/2 pump fuel@20psi=~15 degrees of timing 10 gallons of 91 plus 1 bottle of Torco additive=~16.5 degrees of timing 96 MON 100r+m/2 'race gas'=~19 degrees of timing(might of been more need to check). My feelings about the product are that all its really good for is adding a can to your pump gas to add a small safety margin at the same boost levels you normally run. I wouden't use it with the sole intent of running more boost. For the cost of the product, just add a couple gallons of real race gas(C12, C16 anything 108+ MON) and get better results with the same amount of money spent. I was really hoping that it did what it said on the bottle(1 can to 10 gallons of 93=104 octane) but I knew it probably wouldent work, just been wanting to try it for awhile.
