first of all it's spelled VTEC.... second of all if you want to be able to change your VTEC crossover point then you'll need a VAFC to change it..... since you have a stock GSR i'd keep the stock VTEC crossover point because that's where it'll make the most power, after you get cams and other internal stuff then you can change your VTEC, but it'd be best to tune it on a dyno.. HTH

 

what you refer to at 6000 is the IAB opening up.. on you stock gsr the vtec switches the cam profile at 4500 and the IAB opens up at 6k to allow higherspeed air enter the engine... and hence the difference in sound at 6k...

To change it from 4500 you will need the afforementioned controller, but unless you have some serious mods, you won't get that much out of switching it over... it's at that point for a reason, don't change it unless you have some sort of FI.. and even then maybe..

 

Actually its 4400 and 5800 respectively.
