Greetings ,

I just noticed that there's a missing table that keeps playing with timing on GMC pickups , I used to tune them with hptuners without any problems .

It's related to humidity and it was labeled as " VCP humidity adder dry " in HPT , even though there are humidity spark and multiplier in efilive , none of them did the trick and I had to use HPT .

Please add this table .
