buying my new gears any day now and had a question. in regards to the speedo being off after installing the gears, i spoke with a friend of mine who said that all i need to do is buy the speed cal ($89) device from dallas mustang and install it to fix any problems i may have. is that simple? i've been told before that correcting the the speedo with new gears on a saleen would require reburning the powerflash chip from saleen. does anyone know anything about this? it would a hell of a lot cheaper to install the speed cal than get my saleen cpu reflashed.

Pardon my ignorance, but is it an auto or 5 speed? If the latter, you're fine with the SpeedCal. If the former, you'll need the chip/reflash to adjust for the shift points.
