6.2s in Yukon denalis have AFM/DOD as well as VVT.

6.2s in Denali/silverado/sierra trucks do NOT have AFM/DOD but do have VVT .

I guess the new 14s all 6.2s are DOD

RPO L92, came in 07'-08' Escalade's, and Denali's, VVT but no AFM

RPO L9H, basically the flex fuel version of the L92, came in 09' Escalade's and 09'-13' Denali's and regular 1/2 tons as they switched from the L76 in the NHT and VMAX trucks in late 09'. My 13 sierra has the L9H.

RPO L94, comes in 10' and up SUV's this is basically a L9H with AFM

My L92 that i have for my 92' sport swap came out of a 08' escalade and it does not have AFM

I'm not sure about the eskys but I know that my sisters 07' Denali XL has DOD.

So glad my truck doesn't .

Anyway it's not hard to delete it OP .

Your right ive been doing somw digging around and this year did not have the dod/afm. So i can go with the more aggressive cam without changing out the whole top end?

We will have to get the right info and make a sticky for which vehicles have DOD .

Knowing every setup is different, Does anyone know how much MPG you can "generally" expect to lose when you take out the VVT cam and replace with one of these cams.

I deleted my vvt and actually my mpg is a little better. on the highway I kinda compensated for the gears etc by speeding a little less and i'd say I have 1-2 mpg better then before
city though I think I lost a bit, however I idle it more on a cold start, have the tendency to be harder on the throttle and cant seem to make it threw a tank without a few WOT runs haha

I gained 1.5mpg on the highway after my cam swap with getting rid of VVT. Also had it tuned for the first time when I had the cam installed.

Geez. I didn't expect to hear gains. That's encouraging. I should add that I just cannot keep my foot out of that pedal!!!!

I wouldn't go into it expecting gains... Mine went down, but not a ton. I probably lost about 1 MPG or so, but I also didn't have VVT.
