I saw the article too, I agree it is a gain from tuning, but it is somewhat miss leading IMO. It is going to be from either how the dyno operator rolled into the pull which caused a heavy TQ management scenario, or the car having a locked converter over not being locked. Something to that effect.

The dyno I use holds the car in a set RPM and settles the car to start the dyno pull in the exact same way so that cannot happen. It shows the gains, but not crazy jumps like that one did. GM leaves a lot on the table, but not that much.

 

how do u dyno an auto car at a low RPM? wouldn't it downshift as soon as u went WOT? and what gear do u use on these 6 speeds?

 

You just have to manually bring it up to forth gear, it will stay in that gear unless you slow down to where it automatically downshifts. Sometimes we have to make a change in the program for the lock up to stay on or off the whole time, for better tuning consistency of each run.

The closest gear to 1:1, forth.

 

Good pass
I would love to have an A6

 

Impressive as always....

 

Thanks, We have a bunch of other 2010 Camaro builds that we will post up shortly, along with pics of the first Paxton Novi 2200!!
