so yesterday i was at sac raceway for the first time since i got a ref ticket for my catless downpipe last month.. before i stripped my downpipe off to go back to stock i took my car to the track. my fastest time was 12.9... yesterday i was back at the track and i ran a 13.6 i have no idea why i slowed down i thought maybe cause i was rusty but its weird cause before i went back to the track i changed my plugs, and bought new tires. im gripping now when i launch and everything feels right. i took off my HKS BOV cause it was making me run to rich, any idea why im running slower? i should be running a little faster with new plugs new tires and my stock bov back on right? any advice will help. thanks

 

was ure 60" times the same as before when you ran a 12.9?
