I"ve read on various corvette forums, including this one, that you need to retune to optimize timing and advance and delivery ratios for a new gear set, and the factory is 'tuned' to accommodate the stock gears in the ecu.

Those are minor things that affect the everyday drivibility, tweaks to the chip programming. These are things that can wait until you are completely done with mods, and then have the tuner fix them. Its unlikely you'd notice anything at all even then.

Checked out Randy's and thats where I'll be ordering gear from. Thank you so much guys, thats exactly what I need.
Also,
I'm not calling anybody a liar.. but I've NEVER heard of needing to retune a car when installing different gears other than to set the speedometer. What kind of engine parameters need to be changed for a lower gear???
