Best time i have ever gotten, was a 15.6 when i was stock with my 3.55's , i have never gotten traction again. I have 4.10's now, and cant hook up.
I have managed high 9's in the 1/8th though.. fastest is a 9.8.. With an ok launch.. My traction sucks donkey *****.
My friends Gtech thing got me at 15.3 but with a 3 sec 60 foot.. So i have no clue.. I cant get traction...
