and torque. They say all it is good for is to remove rev limit and top speed. Is this really true? Jim I just bought your software upgrade and I would love to hear your imput on this matter. I heard that you said it was due to enviromental chages etc. but I need a better reason than that to justify my $399.00.Please assure me that this is not true, and roundel mag has no idea what they are talking about. What are your final claims on the torque/HP/ 0-60mph improvement after this chip? Myself and a lot of others are listening. Thanks.
