I guess the question I have for the fake badged cars with a ton of power is... why fake badge it at all?I think my heap is(was?) pretty close. I opted for a spoiler delete and I'm running a different ECU strategy but it had everything else short of the VIN tag. Not so much now with the engine rebuild, TT/SC rebuild, intercooler upgrades, and fuel system upgrades. Now it's much more to your latter point...
Oh there's plenty of old timers that get their jorts in a knot for even less egregious things on old cars. They'll complain if your vintage car doesn't have a perfect factory paint match, you don't have the factory original bolts, you don't have an exact OEM emissions decal on the hood, you've got non OEM wiper blades... All kinds of nit picky stuff.
Personally I love the butthurt my car causes.
For example If it's a 1000 HP Coyote, wouldn't there be more satisfaction as an owner when you rape lower powered GT500s or stock Hellcats marked as a "lower model"?
I guess my idea of what I'd take satisfaction in building a car like that is different.
