I run the SP and the Tekin back to back and the Tekin generates different power then the SP. Both can be fast, but in my hands the SP is faster and my motor comes off about 20-30 deg cooler on every run.

Let me know if you have any questions and I can post my setup if anyone wants to try it.

SP software is 528 Stock and Tekin software is V203
