Default Gearing questions on a 4S brushless converted Revo 3.3

Hey guys, got Traxxas Revo 3.3 that Ive converted from nitro to 4S brushless and I'm having a hard time figuring out how to get this car to run sorta like a Traxxas E-Revo 2.0 on 4S. It has a HobbyWing Max 8 G2 combo with the larger 2250 KV motor.

Now, I realize I can't just run a 15T pinion/54T spur or a 16T pinion/46T spur due to the differences in transmission gearing being that my trans is still geared the way it was for nitro minus the fact that its been locked into second gear but there should be something I can do to get close to the final drive ratio of a 2.0 E Revo.

Right now I'm running a 17T pinion and the stock 38T spur gear for a 2.23:1 ratio but I did order a 19 tooth and a 20 tooth pinion to try with a 36T spur to see how a 1.89:1 ratio works with a 19/36 combo and a 1.80:1 ratio works with the 20/36 gears so hopefully thats enough to make it a little less on the torque. I am running a center diff in this car but even with 20 million weight "fluid", it still tries to spin the front wheels a little faster than the rear.

Any help? Thanks.
