ImageUploadedByAutoGuide1474734694.670825.jpg Finally got a chance to run mine at the track. 4-5 year old h&s tuning and definitely needs some tuning on the PCS but I was happy considering it's a Megacab with 8" lift and 37's.

.... trucks running 5.9 electronics as every high HP 6.7 with the cm2100 has met the limits of that ecm.
What about the 3 tuning companies that cracked the full fueling code on the CM2100? Are they not being used

06-07 5.9 ecm still has more capabilities than a CM2100. There is more to it than just full fuel.

I was asking my tuner about it and he said there are less maps in csp5 on the CM2100 but as far as making overall power it wasn't limiting it to the CM849. I know a lot of guys (07.5-09) aren't going back to the CM2100 after doing the CM849 swap due to the tuning is done in house by those tuners only via ecm and not emailing any tunes.
