Ecu performance upgrade for 03 DB7 Vantage?
Anyone with experience upgrading? I read the factory did an ecu upgrade on the GT version which offered an additional 15hp...
My concerns are; will it cause check engine light issues and/or void my warranty?
Which "chip" should I trust as it seems pricing goes from $69(G-Force) to $1200(Quicksilver/UK)

I cannot figure out myself which ECU upgrade to go after. Unlike with Porsche's, there seem to be no firm consensus as to which chip upgrade (I'm talking about my V8V) is the best. Hope someone can answer your question for your model as I'm not contributing much myself

Any tune is usually $500+..if your paying way less than this and you don't "know the guy" ..look elsewhere for something..
btw how do you have a 2003 V12 DB7 still with warranty..you mean extended warranty??
