2004 GTO - LS1 to LS3 VVT
I see Mast has a stand alone controller. I suppose I'd have to convert over to a dbw setup. Is that all in the Mast computer, or would I need to change out the stock computer?
I have an email out to Mast for some more information.
Worth it? The car is a daily driver, so I like what I hear about "best of both worlds" on TQ down low and HP up top.
