I need a map for my top swap because I want to run a two bar. (YES I KNOW ABOUT THE ISSUES!) I know I probably want to run a Grand Prix L67 MAP because I have a Grand Prix L67 wire harness BUT why are the L67 Monte Carlo and L67 Grand Prix MAPs different? Is it because the Monte Carlo L67 only runs a 1 bar? I looked on Rockauto.com and it looks like the Grand Prix L36 and the Monte Carlo L67 MAPs are the same.![]()
