I have a vg30dett basically stock parts wise,however i do plan on getting what i can out of the engine as is(400hp being a reasonable limit).I am very interested in the megasquirt kit.I like all the features and user friendlyness,not to mention everyone here raves about them.What im wondering is...on searching efi ecu's i decided to check out another name im familiar with,Haltech.Now,can anyone please explain why there is a $1000 difference in these units? Is haltech like the preppy boy bmw of ecu's or something,or am i retarded?
