Burn out issues

I use Innovate motorsports AF gauge that you can daisy chain one of their SSI4 plus, 4 channel interfaces with. The gauge is $250, the interface was $100, the racepack 8 magnet collar was $125, the pocket logger was $80. The DIY auto tune pickup was $25? I used a 2003 350 Z throttle position sensor on my throttle pedal for throttle position. $35? Really just want to know how quick I’m at full throttle. So it’s accurate enough for me. It’s not Racepack, but I don’t have $5000. You get engine rpm from the tach signal port on the msd.
