Anyone else spin on the 3-4 shift?

[Sburns04]

So I was on the highway today cruising in 5th, decided I wanted to pass some slower traffic so I hit the clutch and do a quick rev to 3000 rpm to drop into 3rd and wind it out and nailed 4th at about 6200 rpm and spun the tires pretty good and thought "**** that was pretty cool" lol and it's never done that before my PHP intake spacer install and wondering it really made that much of a difference?

Car is mostly stock besides K&N drop in, PHP intake spacer, weld in flows, exedy mach 400 clutch and 315 35 17 Nitto 555's in the rear with 35psi tire pressure is that normal for a mostly stock car with similar mods?
