I thought I'd update anyone who was interested in this thread.
I bought the GT tuned motor and my brother went for the sport tuned.
I compared the two motors back to back in the same chassis and here are my findings.
The GT tuned has much faster acceleration. It reaches top speed half way down the straight, the sport tuned reaches top speed just before the end of the straight.
The GT tuned beats the sport tuned on top speed, I'd guess by at least 10%.
Two other guys were racing saturn 20t motors. The GT tuned is smoother with better acceleration and a higher top speed.
Compared to 15t firebolt, the GT tuned accelerated much much quicker. But I think the firebolt have been over geared.
Everyone was using the 20 tooth pinion.
