misterp Posted January 26, 2010 Report Share Posted January 26, 2010 Confirmed! I am running the same 2-bar sensor in my truck. Don't forget to rescale your PCM. Mr. P. Quote Link to comment Share on other sites More sharing options...
jlosh20s Posted January 26, 2010 Author Report Share Posted January 26, 2010 thanks guys cant wait to ditch the MAF Quote Link to comment Share on other sites More sharing options...
misterp Posted January 26, 2010 Report Share Posted January 26, 2010 thanks guys cant wait to ditch the MAF I was originally afraid to go SD, and now that I have been tuning without the MAF the truck is FAR more throttle-responsive, economical, and better performing than ever. Don't be afraid to do this, you just have to be committed to getting it properly tuned in person. Mr. P. Quote Link to comment Share on other sites More sharing options...
