If you really want to feel VTEC, boost it.

I am currently having an issue in 2nd gear. When the VTEC hits (at 4800) my front tires break loose so I have to back off the pedal till they grab again which sucks.

With a bigger DOHC vtec you can feel it. In the Teg. Type-R (B18C5) it really makes a difference. There's a video somewhere where you can clearly hear the difference, I'll see if I can dig it up.

Edit: Here ya go.
I know the Integra GSR not only has VTEC, but it also has secondaries (as does the SVT Focus). Does the ITR have the same? If so, the secondaries are generally more noticable than VTEC. The Ford SHO utilizes secondaries for more air flow above 4,000 RPM. The secondaries on the SHO could actually be opened up a little sooner than Ford's programmed, 3950 RPM, to smooth out the torque curve. At the stock opening point, it is not only prevalant by sound, but you can feel when the secondary runners open up.

Here are some dynographs from my stock SHO. In both graphs, I open the secondaries at different RPM's from stock. The graph with the HUGE jump in power had the secondaries open at 5,500 RPM. It shows the restriction in the primary runners above 4,000 RPM. It also felt like nitrous when the runners opened up. The smoother graph had the secondaries open around 3,750 RPM. This makes for a nice smooth power curve for maximum acceleration throughout the RPM range.




EDIT: Thought I would throw in a dyno from my modified SHO. The secondaries are still prevelant with boost. Since I have them opening between the two different torque peaks, they don't break the tires loose, yet it is smooth, linear power.
