Default m6 launch, tire spin vs feathering clutch? Should net same 60ft times without bogging

Alright my best m6 60ft time dumping the clutch was 1.57 on ET streets(non-radial) last night but I bogged after not having any wheel spin(I might add tire pressure next time). Anyhow I kept reading people say to keep from bogging you need a little tire spin(add tire pressure) and others said to feather the clutch. I think they should net the same 60ft times without bogging using both methods.

Think about it both methods keep the rpms up to keep from bogging. Dumping the clutch w/ some wheel spin method will keep the power to the wheels, but have just enough spin to keep the rpms up. Feathering the clutch method you lose power to the wheels, but keep the rpms up since you aren't dumping the clutch on tires that you could not get to slip. Except the feathering method will burn your clutch out faster. Is this not correct?

Also do you think if I up my tire pressure to get a little wheel spin I can still get a 1.57 60ft but not bog?

What air pressure you normally run and what size tires? What RPM do you launch at? sounds like a pretty good 60 ft. to me..

26x10.5x15. It was at 13psi 5500rpm launch. It just seems like it bogs down some after that 60ft time. Maybe not a huge bog but I have to speed back up before I shift to 2nd. Or is this normal?
