We have seen plenty of Heffner Performance twin-turbo Lamborghinis, but it’s always been a drag race, or an owner filming himself with a GoPro. Now in this episode of TUNED, Matt Farah gives us a proper review of a proper Heffner Gallardo LP560. Looking at the man’s workshop you simply wouldn’t believe he’s capable of making 1000-hp Lambos.

What’s more amazing is the quality of Heffner’s work. 1000-hp twin-turbo cars usually expire in a cloud of smoke, or just blow up, after a few minutes under heavy load. But this Lambo does not even seem to be phased!

The twin-turbo kit for this Gallardo makes 950 horsepower at the flywheel, which is like 800 horsepower at the wheel. Fantastic.
