X will run like a beast on 93. ABT probably won't take advantage as much of the higher octane
I ran the X on 93 and it definitely felt stronger then the ABT I ran on 93. ABT wasn't advancing timing as much, in fact it was pulling timing some. But it could have been just a faulty chip.

If you don't need the headroom then the AMS chip is quite smooth, however the X on the H box
Is really close in comparison to the smoothness of the AMS. Just think for the price of the ECU's and the support and updates the X is the better way to go if you must choose between those 2 companies.
