Converted over to Mopar performance with a gold Box and plugs looked real lean had to jump jets from 76 to 88 in the rear. Is this common? I'm running VP110 and the plugs are just starting to look alittle gray.

When you say MPH I take it you mean Mil per hour and not some other abbreviation. I don't have a weather station but Sunday here was very Humid and HOT how much of a role does this play in jet size?

Yes... MPH = mile per hour... temp and humidity have a factor but jet it for the fastest MPH on the day your testing... I will jet up or down 1 jet size for every 25* (if I feel like it to keep it optimized)... 1 jet size wont burn a piston if you were on before
