I am not into Microtech but I happen to have experienced similar engine management previousely that only is capable to activate a valve and not constantly vary angles. I am about sure to fully control the VVTi you need to change management.

In my opinion with your cam setup you will surely have nice power and torque on the upper curves ( probably above 6K depending how wild it is). But this would cost you power and torque performance at low and medium rpms. Also you should know that with these cams, there is a possiblity of a rough with rich mixture which result into an unsteady idle especially if you lock cam angle.

I'm pretty sure "rough@idle" is synonymous with aftermarket cams, ESPECIALLY with the friggin' profile Aras is running. He's gonna need SRB's to get that thing going!



BTW...got these today.

I can tell you what messing with the vvti will do:

left on the car will lose power when boost hits, it may even fall on its face at high rpm. Spool up and bottem rpm range power will be good.
left off you will make as much power as your setup can make (assuming mbt) , but you will lack slight torque under normal driving conditions. In reality thats not gonna matter because you will be able to light up 1st thru 3rd easy regardless.
When we tune vvti via Haltec on our tC or my car, we find it so far to be time better spent elsewhere .
My advice for xbgod, focus on the basics at hand. 30psi tune, dont start tuning with a 8psi wastegate spring (boost controller maxed wont get u to goal). stuff like that. maybe have ur microtec control silinoid to get better spool and boost curve. greddy controller has gain control but still not as nice inputing duty cycle per rpm. that will make more difference than vvti.
