How to tell what is what......I sure can't figure this out.

But its a new opti, new wires/plugs etc. The coil is old. But it does fine at low RPM and on the street it just spins. But at the track...it lifted...I feel it sputtering....wheels slammed back down, it popped and sputtered...I let out shifted and tried it did the same thing so I let out.

Cheacked everything I can think of and I'm just lost, other than throwing parts at it I don't know .....I added fuel in the top end, it did the same thing in the burnout but I had a leak and not able to fix it. (damn oil pressure sensor fitting)
