Did you lose the torque through the tune or the camshaft? A lopey cam like that trades off low end torque for top end horsepower. A good tuner can minimize that but a smaller drop in camshaft is more suitable for a big truck like yours.

that’s the thing, I bought the truck and then immediately had all the work done at my friends shop, so I didn’t have a lot of drive time with it before all the upgrades. You do have a point, Suburbans are heavy, but since the BTR cam is already installed. I’m not taking it out, I have to figure something out to try and get some of the low end torque back.

I have read an account by a fellow with HP Tuners that was able to fine tune his new camshaft and make it lope or not lope.
Now that the AFM parts are gone, a cam swap is easier and you would not have to pull the heads or the top end off, just the front.

I am hoping for the very same thing. Im sure if we go through the afr numbers and recalibrate for the new CAI Intake and catback, we can smooth things out and restore a little bit of what was lost. As far as the cam lope is concerned, i like it where it is, but if we have to knock it down to restore some bottom end, then so be it.
