The 203 and 204 both are close for a map to run till you get it on the dyno for a custom map. Its important to get a map made for your build. Matt Gross has a web site with several maps he did for a $50.00 bill...the web site is hd-maps.com I believe, there might be just what you need there.goldenglide said:I am trying to come up with which map to use on my SERT and HD lists only their cams.
Which one should I base my MAP on?
P.S. Build is as follows: 04 Ultra with; 1550, Flat top pistons, 37G cams, SERT, SE slip-ons, stock heads.
