Re: Timing..
I know that timing retards as boost increases, but when I hit max boost 30 psi yhe timing is still falling. I guess im not understanding your question? What map am I using? Do you mean maf? If so im using a 3 1/2" gm maf. As for the load holding constant. Im 80% sure that it is. Checked for boost leaks 2 years ago, none. I know the weather can effect vaccum hoses over time so ill double check those, and do another boost leak test over the weekend. Checked compression, 180 across the board. What am I missing?!!
