Cool, go for it. Did you get the Trans Tcm unlocked? Didn't think that could be changed unless it was unlocked as King says that's the only way to open the throttle all the way. Maybe I miss understood that?

That isn't exactly what I said. Yes there is TM on the ECU side if you bump into that will close the throttle. The stock TCM TM doesn't allow the Throttle to fully open off the line until above 5500-6k rpm or so depending on how much torque you make. There is a difference between throttle closing and throttle limiting.

Every stock TCM tune car I have delt with so far was this way.

Here are some screen shots of my brothers 2019 A10 ZL1.

1st pic is basically stock with flex sensor and stock TCM tune. 1st and 3rd gear limit throttle at the bottom of the gear.

2nd pic is with headers, cai, 95mm tb, E50. It's getting much worse. pretty much all of 3rd is limited to 50% throttle and even 4th just a little.

3rd pic is all in. Ported Blower, 2.1 pulley, cai, 103tb, fuel system, E50, TCM tune. Throttle open all the way in all gears. The car 60-130's bottom 6's and traps over 135 full weight on 20" forge lines.

Mine was exactly what the first pic shows. On all runs.

I was also getting TM from the Minimum Spark table under the 2-3 shift. I was commanding enough change from the OEM file, the reported TQ was greater than what the TCM allowed, and I'd get a trickle of TM for a little bit. I noticed, after the T87A that it was the limit in 3rd. I fought it for months, until these conversions became available to us.

Sorry if I missed the point on your comment. Shit happens when you don't totally understand the TQ management tables and I don't but will try and work on learning more. But I want what you have in the 3rd pic. Here in mid Missouri we call that balls deep in the neighbor's sheep.

Satinsteel1le - did you have to upgrade your bumper heat exchanger?. How are your temps with the magnuson? Thanks

I am similar but with the eddy 2650 and I can tell you the biggest change is consistently low IAT even with hot lapping.

I was thinking with the better cooling the stock one would work ok
