My first time I ran a 16 flat at 91mph and a 2.2 60 all stock. I had no T/C switch just turned it off in car... launched at 4k rpm dropped clutch spun wheels bogged then caught. I shifted at around 7100-7200 no powershifting just shifted really fast and dropped clutch each time. With some better tires and a few mods I could pull low 15's high 14's now I know how to drive my car better.
Personal best run of 15.5 at 90mph... T/C switch and still dropping clutch at 4krpm. The race season is over here in minnesota in my area, but next spring ill have some mods done new rims and stickier tires so im shooting for high 14's. Im also going to try dropping clutch and feathering off the line.
