I have the exact same experience here. Same year and auto, same tuner too. It does seem almost..dare i say it slow...after like second or third gear, you can hear your cars exhasut lighten up too, i think that it is a combination of the eco tune maybe, i have the performance tune also they both seem to run through the first two or three gars pretty quick leaving your last one sluggish feeling.

Does anyone know how we can tweak the tune to make it more responsive?

It's not something you can adjust for with your handheld.

Something here I want to try is to remove the 87 program and go with the 91 program. It will take a couple of days to get the fuel level down far enough to fill up. There has to be an answer somewhere. If its something I have to live with fine, but if its something we can change..lets change. Now I do want everyone to know that this set up from Brenspeed is a killer. The differance in the performance is out of this world. You just have to love these Mustangs!

did your delet plates help or hurt yours on bottom. Removing that restriction might be what's needed.

Forged bottom end, Ported heads, Saleen super charger, 2.8 blower pulley/15psi, Dual stage water to air intercooler, AFCO heat exchanger, battery relocated, Twin GT500 fuel pumps, T-56 trans, Aluminum flywheel, Aluminum driveshaft, 3.73 rear gears, Eaton TruTrac Diff, TA Performance rear end girdle, Racecraft suspension system, UCA, LCA, panhard bar, 15" slotted front rotors w/ 6 piston calipers, Carbon Fiber front splitter/rear diffuser, and bunch of other stuff
RWHP/RWTQ is adequate

When I removed mine, I also installed the AR headers and I didn't really feel any lose in torque. And no more power transition when passing 3k rpm.

its not the tune or the car and changing it from 87 to 91 wont make that much of a diff.... this is just a matter of the first two gears being much shorter than 3rd and 4th...if you install LT headers than you will loose some low end trq but you wont care with how much it gives you on the top end

JLT II, Brenspeed 93 octane tune, Motive 390's, Steeda UDP, Pypes long tube headers, o/r X, Flowmaster American thunder series, Helix throttle body spacer, 12.921 @106.42 2.178 60ft

Yup, same thing, 06 auto. Tillmans tune. A pedal reset helps for a bit, maybe a few miles or so, then it acts like it has no torque from 1.5k to 3k. (and I mean NO TORQUE) Worse in weather above 40 degrees F.

Could be a vacuum leak. I had the same problem when I installed my new throttle body, found a little gap between the intake and new throttle body. Applied some rtv and problem went away.
