This is post coilovers, catless downpipes, and new softer tires.

Still haven't bested my 12.4211 on just a 3bar tune and CAI?

Cool. I was just wondering about that for that 1.76 60' you got. 👍🏼

Here's the video

I was just out last Friday and had no issues with spinning the tires. Maybe the track was prepped good I dunno. Squeaked the tires some but no spinning. I had a half tank of fuel though. Do you have trouble normally if you leave tires at 32psi? It also seemed like if I held the brake boost too long before I left the line it had less power. Are you guys holding your rpm or as soon as you get there you are leaving the line.

At Milan the prep seems to be better with big tire guys there spreading it out...only time I've seen traction issues were at Customer Appreciation Day when there weren't many big tire cars doing them nice burnouts.

Seems like my 60' has gotten better each step I've taken in lowering the tire pressure...at 25-26 psi lately

I seem to be the last guy to fully stage each time, so the boost isn't being held very long at all...at Milan the tree goes live as soon as 2nd car stages

At Cecil where I go, they have a top 10 list now. So there were call outs when I was there. They go over the track and prep it before they race. My 60ft right now is a 1.87 I think, why would lowering the pressure cut a better time if you don't have traction issues to start?

Issues I'd classify as way too much spin, sometimes causing people to go into limp mode.

Going from where I started at 29 psi down to current levels has gotten me a 1.760 60' compared to my mediocre 1.8's prior.
