Tuning Tips
1. For the first run, the rear tires were left at 16 psi. From there, Justin would be able to determine whether to add or drop air pressure. In this instance, he found the ideal launch for his combination was to leave the line at 2,000 rpm, while feathering the clutch.

TIME: 12.1 at 119 mph

2. Moving on to the second pass, Justin added 4 psi, changing the total to 20 psi. Justin explained: "With more tire pressure, there will be a greater chance of spinning the tires." Still, he felt confident that his previous launch at 2,000 rpm would suffice. His change dipped him into the 11s by running 0.16 quicker with the same trap speed.

TIME: 11.94 at 119 mph

3. For the third pass, Justin left the 20 psi in the rear drag radials. "I went for a more aggressive launch at 2,500 rpm," stated Justin. Unfortunately, by having to slip the clutch quite a bit more at the line, he ended up slowing down his Corvette by 0.13 seconds.

TIME: 12.07 at 119 mph

True Street 11 Second Index
Edgar Perez's story is a bit unique. Not only did Edgar actually need to slow his car down to remain in his 11-second index, he did it without even popping the hood, instead he uses the latest tech craze-"With my iPhone!" he exclaimed. "It's great, all I did was download an Excel file to my phone and I just punched in my times to get a predicted outcome." Add in the fact that his car utilizes an automatic and Edgar's consistency is generally dead on. Edgar uses this advantage to stage the car either shallow or deep to adjust his e.t.'s as needed. Edgar went on to say: "I can trim 0.15 seconds off my time if I need to."

Tuning Tips
1. With a shallow stage on his first time trial pass, Edgar managed a smoking 10.93 at 122 mph pass. "I shallow stage to essentially make the track longer," says Perez. He stalled the car at 2,000 rpm and let it all hang out, remembering it's an average of the three passes. He knew the Corvette needed to slow down for the next two runs in order to qualify.

TIME: 10.93 at 122 mph

2. Edgar's second pass had played out as he predicted. Knowing he would need to "slow" the car down, he staged the car very deep-essentially making the track shorter and therefore running a predictably slower time. He again launched the car at 2,000 rpm.

TIME: 11.18 at 123 mph
