I Want to DisEngage my VTEC!!

ok, i know the subject sounds stupid, but i was wondering of i could take out my VTEC all the way, i mean it kicks on at around 5.5k rpm anyway so that doesn't help.. my turbo is spooling like crazy by then anyways. But the main reason that i want to disengage it is because when VTEC engages,, your timing curve goes really high therefore making your motor even more prone to detonation especially at high RPMS, but i know i'll get a CELL and then go into limp mode if i take out the VTEC. Well my friend can reprogram ECU's, my ECU is still programmed for Naturally Aspirated, so right now my timing is way high anyways, but im planning to up the boost to around 8-9 lbs, so i need to reprogram it back to stock, but i was thinking,,, hmmm..... maybe i can have VTEC engage at around 7500 RPM so i'll never have to worry about it and i'll get no CELL!!!! what you guys think??? did i discover something?? most motors blow at high RPMS, but i think with the sufficient amount of fuel and no VTEC... i'll be able to boost 8-9lbs safely!!! any comments on this subject will be greatly helpful, later :p
