You think that is impressive!!!! Try the ultimate in tuning. Use an odonnell turbo plug. He only makes one .12 turbo plug. Therefore no matter what the temp, humidity, nitro, planetary alignment, plutonium half-life, gravitational pull, or even whoever wins this years Tour de France...... you have the right plug in the engine.
I am not making fun of you, I am just trying to have some myself. Yes, he does only make one plug in each category. 1/8th standard, 1/8th turbo, 1/10th standard, and 1/10th turbo. All work quite well (haven't tried the 1/8th turbo yet)
