im ordering the powerflash cable from vector to do my tcm .i heard the tcm tune is almost same affect like the ecm tune,especially in the six speed autos....
Chris... the guy from WAMS, whose tune you were talking about here wrote the tune for Vector when he used to work there.
one question.. if i get the 91 octane choice, how does that add more MPG? doesn't a higher octane level decrease the mpg?

The higher the octane the slower the fuel burns. also the further you can push the advancement without pissing off the knock sensor and the more HP you can make
