Not to bust your bubble but it seems like the gains were from adding more nitrous. The Da did suck. What A/F are you seeing on a pass. I would get those tr7's in. I sprayed 200 on TR6's once. I melted the tips off with 10 degrees of timing out. It cost me a stock bottom end. I here they are like glow plugs. I now drive the car N/A with the tr7's and spray it. I have learned alot from ATV and shiznity. Pull alot of timming with correct plugs and dial in the A/F. Congrats on the new best.
