Folks,
I have a LS1. If I swap my 1 Bar MAP sensor for a 2 Bar do I need to program the computer right away or can I do it a week or so later? So is it basically backward compatible if using the 2 Bar as a 1 bar? Thanks.......I do know that if I want to benefit from it then I need to update to a 2 Bar OS in HP Tuners and adjust a few tables. I just want to do this a little later
