I wrote this page up a while ago for my '85 Z28, most of the info will carry over to the vette.

Bypassing the MAF years and jumping right to a speed density '90-'91 would be a better choice. Vette's have to deal with the dash computer though so keeping the stock ECM to run it in parallel is an option.

I stuck with Speed Density and have to try real hard to remember how to tune MAF systems...
