And you shouldn't, probably best to find a builder that builds a 600 hp sbm all day long also.
But a good chunk of people don't, They see TF ad or in a catalogue, online see the price ain't too bad and TF says they can make 500 + hp, out comes credit card and sold. You don't think the same person would buy a step up over TF for a reasonable price also if they had a choice?
How many of the question here are people needing help cause they didn't plan it out too well, or their planning it here but don't want to listen to a more modest build.
