what is right ?????
what is your guys opinion on what is more accurate or which one would you trust a mechanical phantom boost gauge. or while tuning on chrome the read out from that program ? they read about 3 to 4 lbs dif. gauge will show say 20psi and the program will show 17psi

What is your elevation? I'm at 5000+ feet here in Colorado and a relative pressure gauge (ie boost gauge) will read 2-3 psi more than an absolute pressure gauge (ie MAP sensor). I would tune by the pressure that the ECU reads, since that's what it's doing fuel and ignition based on.
