Hi i'm new to hptuners. done a few tunes on megasquirt/tunerstudio. ive been reading watching videos and exploring vcm editor. I have some questions regarding turbocharging my 07 uplander 3.9 v6 flexfuel e67 ecm. my research has led to me to the conclusion that SD tuning is the way to go and to ditch the MAF. That being said the majority of hptuners information I have found pertains to the v8/ls engines not a v6.
1. Do I have to upgrade to a "2 bar OS"
2. Is SD tune the way to go?
3. How do I tune the "main" fuel/Spark table in vcm editor
4. consideration if choosing to use maf sensor in turbo application.
Thanks. -James
