What about the factors for air between the stock pulls and next trip to dyno with the mods.

Hey Ted, do you have any stock dyno pulls that you can post that shows the torque being held at 280 under 3K? Thanks!

Wow! That's a pretty obvious torque restriction below 3200! This was from an LS3 correct?

The Lowest cost most featured I can send you is the Predator, PM me for Pricing.

It has user tuning ability and can accept Custom Tunes, Makes a nice Christmas Present to Self.

According to the graph, it looks like tm is kicking in at around 2500 rpm and holding until 3000. Approximately 20 lbs torque is being freed up from a tune alone in this rpm range. Correct me if I'm reading it wrong. This was the info I was looking for, I guess I just didn't ask the right question. Thanks Ted.

TM is a Linear graph, starts out at 85 ft lb.

And what is GM's logic on the throttling TQ until 3000 RPM's? Breaking parts?

Can you over lay a stock graph vs. your tuned graph so we can see the gains? I just see one graph there so we don't get to see much.

So with a tuner and the tunes that reduce the torque limitations at certain RPMs, what does this do to the StableTrack, Traction Control, Launch Control systems, i.e., the button in front of the gear shift? Is that button now disabled or do those systems still work normally as always? We're just talking about setting the computer to allow more torque during a given RPM range but if the rear wheels break loose, the computer will still reduce torque in order to maintain traction when those systems are engaged right?

All pulls are done with a stock car, unstrapped then modded, then re-dynoed. The Dyno also has a weather calibration that is instantly updated.

Here is one with the torque management turned off.
